How come Rue could knock the door down but Fezco couldn’t?

This question has been wondering my mind for days now… and I’m still not over it.

Rue knocked her door down in two seconds and Fez couldn’t even make a dent when Ash was in there. Which led to you know what.

How is that possible ??

We needed Rue Rue there in that scene because I know she would’ve done anything to save Ash.
