A4/No.4 will be around, feeling very unsettled by the ship. Space is going to remind her of being back "home" on her satellite base. Of course, A4 will just keep being A4 and act like nothing's wrong by covering it smiles. Unfortunately her powers will be useless for investigation, unless you're reckless and damage your clothing... she may be able to provide a spare set.

Her priorities are going to be attempting to bust through the locked doors and following the noise. She's tougher than she looks, so if you need another person for breaking things open, she's your girl!
