Well, she's gonna have a fun ability. Probably named something relatively direct. Wall Walk? Maybe it'll go the way of My Hero and name it Permeation. Weird that the showed off some energy though. We know she had to be able to use it on herself to get to the slowest group first. Bukkake Brazillian Jujitsu Gal got phased in mid-air, so she was probably trying to choke her out. It had to be something Jammer couldn't Jam, which seems to be touch based abilities? If it was a teleport ability, it would have to be short-range on other targets, and the running away would be even more fruitless.
Mostly mental rambling aside, I can see why they'd consider it an 'Invincible Ability' for the Field Dungeon. Easy incapcitation and mostly unrestricted movement is a great combination.
