Red's little wing display doesn't intimidate Aconite. In fact, it's one of the most exciting things that's happened to her in days! Sure, Shura and to a lesser extent Shishi, play with her, but they were so much bigger. Also, they didn't have wings. She spreads her own wings out wide and making a low, chortling sound of growl. If she wasn't so small, it might be a terrifying sound, but it just comes off as a cute sort of growl. And then she's promptly dashing off in an obvious attempt at getting him to chase her.

"It ain't the pukin' you got to worry about with him. He gets sentimental if you're not careful." Shura says flatly, clearly having been a victim of Strange's feelings. She needs a drink to try and chase those memories away.
