Hi-Five Ghost never seeks the spotlight. He doesn’t make a
 fuss when his friends get into yet another absurd scrape, and he’s always ready
 to do his bit to put things right, but his participation rarely makes much of a
 difference. The most common role for Hi-Five Ghost is as the guy who falters in
 the early going—a minor plot-mandated sacrifice meant to prove the seriousness
 of the threat that Mordecai, Rigby, or Muscle Man ultimately overcomes. Indeed,
 even in stories where Hi-Five Ghost forms a featured quartet with those guys, there’s
 no guarantee that he will get so much as a line. He’s fundamentally a
 background character who just happens to hang out with Regular Show’s main characters. After all, he’s the only regular
 character whose name is just a description of what he is. But it’s not even as
 though Hi-Five Ghost spends all his time trying to get people to high-five him.
 Such an obvious gag would make him a one-note character, but at least that
 would give him that one note to play. As it stands, Hi-Five Ghost is just a
 dude, and he’s a fairly nondescript one at that. 
Given all that, “The Postcard” could never hope to be a piercing
 look into the depths of Hi-Five Ghost’s soul. This episode can’t do for Hi-Five
 Ghost what “Bank Shot” did for Rigby or what “Power Tower” did for Muscle Man, because such
 stories require character arcs that Fives is not equipped to undertake. An
 episode like “Bank Shot” succeeds because it creates a scenario in which Rigby
 must face the consequences of his braggadocio and overcome his deep-seated
 self-doubt. What happens in “Bank Shot” might be Rigby winning a silly arcade game
 against a total jerk, but what matters in the episode is Rigby becoming a better person, if only slightly. Indeed,
 because Regular Show is so concerned
 with the young adult’s worldview, a solid chunk of its best stories are about growing
 up and maturing into a more complete person. That formula doesn’t work for a
 likable but underdeveloped character like Hi-Five Ghost, so “The Postcard”
 turns that potential narrative weakness into the story’s fundamental strength.
  
After all, “The Postcard” only works as a story because
 Hi-Five Ghost is the exact same person at the beginning of “The Postcard” as he
 is at the end of it, a fact that’s particularly impressive when you consider
 that the episode spans four years. He and Celia are in a position to pick up
 exactly where they left off—heck, she didn’t even dye her hair a different
 color after all that time in Prague—to the point that their ultimate reunion
 features a line-for-line callback to their opening exchange about the quality
 of the café’s Americanos. Hi-Five Ghost’s life is in stasis, but it’s the nice
 kind of stasis. Consider the episode’s first present-day scene, in which Benson
 distributes the day’s mail. In what has to be the most wonderfully, hilariously
 immature joke in the show’s history, Benson reprimands Mordecai and Rigby for
 their home-delivery subscription to Fart
 Weekly, the cover of which prominently features a naked butt breaking wind.
 Beyond the fact that I can’t quite believe Regular
 Show got away with a joke that crass,
 this moment matters because it reminds us just how much Mordecai and Rigby
 still have to grow up. The subsequent dialogue, in which Muscle Man asks about
 his tax return, is a rather dry exchange, but it confirms that Mitch Sorenstein
 is much closer to adulthood than his coworkers. None of those three characters
 are quite where they should be or where they want to be. Only Hi-Five Ghost is
 in a stable enough position to go on a romantic quest this goofy.
   
And make no mistake: Hi-Five Ghost and Celia’s love story in
 “The Postcard” is deeply, deeply silly. It’s fitting that a character defined
 by his willingness to go with the flow would meet a woman who, by sheer
 coincidence, shares all of his thoughts and opinions about everything. The romance
 montage never tops the hilarious specificity of the initial gag, as we learn
 the pair share a passion for down-tempo electronica, but this is a
 character-building exercise as much as anything else. Hi-Five Ghost is so
 agreeable and enthusiastic here that it might seem insincere if he were any other
 character. And, with that statement, “The Postcard” establishes specific contours
 for who we understand Hi-Five Ghost to be—and those parameters can then be subverted. Hi-Five Ghost is
 so naturally positive that he responds to Celia’s lack of a cellphone with a
 joyful “Me too!” before realizing the sad implications of that situation. If
 someone in the audience didn’t care about Hi-Five Ghost before that moment—not
 that I seriously believe anyone so callous could exist—then he or she should be
 won over by his heartbreak when he realizes he might never see Celia again. And
 that momentary gloom just makes it all the more endearing when he agrees to
 Celia’s cockamamie postcard plan, happily observing that it’s the most logical
 way for them to stay in touch.
  
Hi-Five Ghost shows quiet desperation throughout his search
 for Celia, and he gets in an emotional breakdown or two, but “The Postcard”
 realizes it can only push the character so far. The episode is as much about
 Hi-Five Ghost’s friends rallying to support it as it is about Fives himself. The
 story allows this bond to go uncommented upon, as there is never any question
 that Mordecai, Rigby, and Muscle Man will do whatever it takes to help their
 friend reunite with his lost love. That’s significant in its own way, as pretty
 much any park staffer would be moved to thank Mordecai and Rigby for their
 unexpected assistance in such an endeavor. Hi-Five Ghost can take it for
 granted that his friends have his back. Even then, they can’t hope to match the
 kind of support offered by Fives’ brother Low-Five Ghost, who flouts every police
 regulation in the book in order to help his brother.
 
Low-Five Ghost’s insane decision to drive through the mall—it’s
 cool, he used his loudspeaker to tell everyone it was a routine procedure—is one
 of several terrific gags in “The Postcard.” As with other recent episodes, this
 story has a crazed energy to it that makes each joke that much funnier. There’s
 the quick cut to Benson holding up the issue of Fart Weekly, but that can’t compete with the subsequent blitz of
 reminders that, yes, today is March 20. In the
 long, distinguished history of shows using news broadcasts to impart vital
 information, it’s hard to imagine any quite as gleefully pointless as a guy
 screaming the date three times over.
Speaking of pointless, Wes and Wesley’s obsession with
 chop-busting is a tangent from the main story, but it’s the sort of
 digression that Regular Show does so
 well. Low-Five Ghost’s warning that our heroes will have to chop-bust the
 forensic investigators right back feels like it could be setting up some weird
 side quest, but “The Postcard” keeps the interactions relatively grounded. The
 episode does suggest a potential personality trait for Hi-Five Ghost when he
 gets inordinately real with his chop-busting, but his momentary inability to
 read the room is just the setup for some particularly fine chop-busting from
 the forensic investigators. In some future episode, Regular Show might do well to expand on the idea that Fives is sometimes
 too blunt for his own good. But for now, it’s time to let Fives have his happy
 reunion with Celia. If anyone on this show has earned that happiness, it’s him.
Stray observations:
 
- I don’t really understand why Wes and Wesley would need to device a complex mathematical equation to solve just what Celia wrote in her postcard, but I approve of their thoroughness.
- Seriously, Fart Weekly is maybe my favorite joke in the show’s history. (I’m very proud of myself.) It’s not just the utter brazenness of putting a guy’s butt on the cover; honestly, I think my favorite thing about it is that it’s Fart Weekly instead of Farts Weekly. The latter suggests a magazine simply devoted to the week in farts, whereas the singular fart suggests the magazine is concerned with the deeper philosophical meaning of the very concept of the fart. (I continue to be very proud of myself.)
