[His enthusiasm about whatever's going on rn is minimal at best. But he has other things to focus on, really - mostly, being out and about after a few days of mostly keeping to himself (readjusting to everything, being overwhelmed at everything, you know, the usual).
For now, anyone passing by today will notice Aramis and Porthos training together. Not too different from how they're usually messing around with training and practicing, really! Except, oops, Porthos seems extremely focused on it as they're sword-fighting. And Porthos is fighting a little more aggressively than he normally would be. In fact, he just punched Aramis pretty hard, catching him in the stomach.
If you were thinking about talking to him, you might want to wait until he isn't quite so focused. But he'll be available to talk later, once he and Aramis are done dicking around.]
