You can't spell New Year’s Eve without Steven (Universe, that is)

Here’s what’s happening in the world of television for Monday, December 31. All times are Eastern.
Top pick
Steven Universe (Cartoon Network, 7:30p.m.): The episode note for tonight’s Steven Universe simply says, “Steven throws a party to bring his family together.” That sounds like a classic Steven set-up (“Together Breakfast,” anyone?). Yet we’re concerned for Garnet, Amethyst, and Pearl (and Steven!), becayse both the title of this episode and the stakes of the “Diamond Days” event lend this one a somewhat ominous tone. That title: “Together Alone.”
