Strange is radiating hostility right back, though his is fierce stubbornness. He's right. He knows he's right! Lapis hasn't done anything to prove she shouldn't be trusted and Peridot likes her too much to actually realize it. He matches her blank expression with a determined one of his own.

Before Peridot gets too far away where he has to yell it, Strange says, "When I see Lambert next, I'm going to tell him the truth." He starts to flap his wings as he takes to the air. "You should worry about yourself instead of me."
