AVClub:Now this is more like it. There were leaked images from “Barn Mates” a few weeks ago (maybe more?), so it’s not like it’s surprising to see an entire episode devoted to Peridot trying to win Lapis over as a roommate. But that doesn’t make the premise any less fun. Without any world-threatening crises to take care of, Steven Universe can tackle what’s basically a low-key sitcom plot head-on, and absolutely nail it. “Barn Mates” is an effectively emotional, funny episode, with some solid Steven material, more character shading for Lapis. Also, it’s maybe Peak Peridot.
