I see him getting into his share of scrapes, and eyerollingly so because he seems to have never grown up and realized that heroing is dangerous. She's scared that he will get himself killed trying to reform his 'team', or something else.

Oddly enough, she might cling tighter given that he has gotten himself into this situation with the Empire. He's on Earth. He's safe as long as he doesn't have his Cellular and isn't running towards danger.

(And if she's not careful, she'll have a pirate captain kicking her door down if Gai doesn't convince her to let him go.)
