[ This isn't the first time he has been asked this question, but taking it into his hands and turning it over, he thinks his answer is different. Comfortable isn't the term he would have used, because when they arrived, he had viewed this as simply another mission. In some respects, he still views it that way, but there is more to it than that.

It has given him the opportunity to meet Cal and help him in his training. It has let him step away from the front of the war — or the end of it, anyway — and remember what it is like to be a person instead of a soldier. More important than anything else, it has let him reconnect with Anakin.

Obi-Wan leans back, pushes his damp hair out of his face and looks up at the hazy wooden planking of the ceiling. The stubborn fringe of his hair stays slicked back for a moment, before falling heavily back against his brow. Is he comfortable? ]

I am... grateful.

[ He admits at length, and closes his eyes, reaching out into the Force to feel the life of the people milling around them beyond the sauna. Reaching out to feel Cal, and Anakin. Reminding himself they are whole and safe. ]

I cannot understate all that I have lost in my timeline. This place has given me opportunities the war never would have allowed. When I return, I doubt anything will change. The wheels in motion cannot be stopped for me — but there are others who may be able to change the course of history with a better understanding of themselves and the world around them.

[ A beat, and he opens his eyes again. ]

Those of us that leave will leave as better versions of ourselves.

[ The suggestion being that, maybe, some of them won't be leaving at all. There were whole civilizations in these train cars. Obi-Wan doesn't think they exist simply as happenstance. ]
