so duhm of Laurie to pull on Michael's mask
She says "I just have to be sure" before doing so.
I get her wanting to be sure she doesn't kill the wrong person again. However, the situations were different. While it's far-fetched, you can understand "Michael's" closing actions in H20 as being a distressed innocent. If you're wanting to reach that far.
However, here, he's actively chasing and attacking her, so it seems like that would be enough to let her know
