Stanley managed to defeat everyone on the medical floor. The only person there that caused any trouble to him was a man who could control the clothes of others, wrapping them in them.
The main trouble was that it reduced visibility a lot, which affected his ability to stop time or reverse time for certain individuals.
The others had various powers, but none were strong enough to stop him in the smallest way.
Once Stanley defeated them all, he quickly turned toward Amy, who knelt atop a man who could do nothing but struggle. The man was completely pinned down to the floor and nothing he did helped him get out of it.
Stanley slowly moved toward her, very much confused about the entire situation. How was she so strong? Never in a million years could he have believed that Amy was strong enough to blow away ceilings with a single punch.
