Adler finally came back after the whole perseus and stitch thing back in Europe of course he was happy to see you again after such a long time why wouldn't he be? you're his partner the one who decided to wait for him even after all the time he was apart from you how far apart you two are but he's finally home

although it wasn't surprising he was a little tense after everything he's been though he's a veteran serving in Vietnam and in the cold war he would obviously come back with a few issues and problems which he tried to hide not wanting to burden you

and not wanting him to be so stressed all the time you two went on vacation to a tropical island to relax

Adler lits a cigarette the moment he gets off the plane and looks up as you walk down with the luggage "so this is supposed to be relaxing? for us?" he asks as he gets up and grabs his luggage to make it easier for you "we're getting older I think what we find relaxing is different" he muses with a soft chuckle
