Steven Universe - Right in the eye.

And in that moment, Lars was finally redeemed.
I knew everyone was going overboard with their hatred for Lars. Ronaldo? Yeah, sure. I can believe that; his character seems generally flat and poorly-done. But Lars was written specifically to be an anxiety-filled angsty teenager, so of course he would come off as cringy. Unlikable, sure – but his arc has finally reached a turning point.
Unfortunately, I have my doubts about Ronaldo. His one true moment of character-building was thrown away for God-knows-why (back when Steven and the Crystal Gems had the opportunity to show him the truth, but ended up encouraging him to stick to his conspiracy-theories). He's had maybe two good moments, but they barely amounted to anything.
