It hurt not being able to go big and crush the thing. Kamala isn't used to being powerless. She knows a strategy when she sees one. She makes the choice not to interfere.

One thing Reims taught her is how to move on even when your heart is breaking. It also taught her how to always be useful. That's why she is tapping the shoulder of a guy she doesn't know. She may not know him, but she sees that look in her eyes enough to know what it means. He's trying to help too. More importantly, he lives here probably so he can find stuff for her. "Where do they keep the broom? We need to sweep this up before someone gets hurt."
