[As anyone who's familiar with him should know, a happier Aramis is a melodramatic Aramis. So while he was initially perfectly happy and content with the big change, by now he's grown bored of all this pretty scenery. He starts to get whinier as nighttime arrives, since the caves do get very cold and dealing with some chill is evidently the worst thing that's ever happened to him.]
[So you might find him in one of the large common rooms where a big fire has been set up, sitting so close to the flames he's probably at a risk of getting burnt, grumbling about the cold and working on mending a shirt that got torn by some overly-enthusiastic baby dragon.]
