LOL. I think it’s more to do with he can seem pretty intense when warming up on the bag or just the general way he moves. Most of the girls haven’t really been around real fighters and finding out that’s what they’re facing off against or hearing him pound on the bag can be a little intimidating I guess, lol.
Lauren in particular IIRC was chatting with Darrius between shooting still photos while Rusty was warming up and the sound of him punching gave her some pause, and she was already familiar with him!
Here’s one where you can see one of Jennifer’s feet lol
