This is a fairly straightforward plot-focused episode, wherein Steven considers serious Gem matters with the same sort of care as Connie’s favorite book series.
Winter Forecast
This episode features a neat concept taken in increasingly serious directions (but it all ends well).

Future Vision
Garnet tries to connect with Steven by sharing her secret superpower…and fails spectacularly (or does she?).

The Test
This is a deceptively simple episode that marks something of a turning point in the narrative.

Alone Together
This episode is just quintessential Steven Universe, and I’m pretty sure it’s what finally made me a fan.
Warp Tour
Big changes are looming on the horizon, and Steven is the one with the unfortunate task of warning the other Crystal Gems.

Watermelon Steven
This is one of those episodes that just takes an absurd premise and escalates it to insane levels…and somehow manages to have a heart in there somewhere.
Garnet’s Universe
This episode is mostly just a pastiche of Super Mario and classic children’s anime. You probably already know about how much enjoyment you’ll get from it.
Fusion Cuisine
This episode manages to combine absurdity with just enough sincerity that I can forgive the contrivances that lead to the whole scenario (and the awkwardness which subsequently ensues).
Secret Team
How come the best things in life are things you can’t tell other people, because you’d get in big trouble?
