Hey there, I can offer Ian as a test subject for Eva's power. Whether it was accidental or on purpose, is up to you. But I'd love for her to find out that he was a former US Navy SEAL. Ian loved being a SEAL, but ultimately his career ended prematurely due to being injured during the war. It's a touchy subject Ian never discusses and whenever anyone tries, he changes the subject.
Ian has been in AA for seven years as a Handler, so I think Eva revealing his past would cause quite a conflict for him.
