[@Leotamer] Let's see...I'm not sure if her age is right for a masters, but given that she mostly was homeschooled, she might've gotten to college early.   She joined the organization at about twenty-five, I think.  Mr. Welsh vanished one or two years ago, so that's a year or two with them both there.  No idea if Alex heard anytyhinbg about Alys from hos dad -- that's between you and him.  And if he doesn't insist on Alex she'd stick to the more formal Alexander.

[DepressedSoviet]  does that timeline for Alys sound right to you?  My guess is she graduated at twenty-three, and joined up at twenty-five.
