I'm not sure Evilyn knows how to tone down her clothing. I originally wanted to show them leaving the building, but it didn't fit into the space I had here.
Why did Evilyn change at all? The look she's sporting in panels 1 & 2 (and the previous page) is fine for blending in. Maybe a pair of sunglasses could help, but that's it.
Annie and Tabitha will activate their suits, Arim is super-durable. Evilyn has to be dressed to fight.
