Well, any info is probably in his journal (Spoilers abound) as well as a not-quite-essay on why I don't consider the second game canon. >.> (Which in turn, also explains why I play Alex the way I do...)

That is an interesting question too--b/c we have a werewolf on board too, with a good nose. I'd go with 'interesting', but there is a definite hint of 'danger' around him. So Ein's reaction should be 'observe, and be wary'.

Alex has no need to make enemies on The Station, and--aside from pissing some people off (where he's still lower on the count of that than Tony Stark)--he's been getting along reasonably well.

^^ Feel free to talk with me anytime for shenanigans and stuff.
