And judging by the last shot of this scene from Astarion Origins, he's crying.
I interpret that as curling himself in a ball so his face is better hidden from the sun. I find the spawn ending in Astarion's Origin extremely satisfying, especially with some details that were added with Patch 6. What I dislike about it, is the implication of attacking a bound person in the sewer, and that Wyll and Karlach can't sort their stuff out on their own.

Gale's baseline that stays the same throughout the game and in every ending is, that he desires to help others, especially help other to better themselves and improve their own situation. In regards to the "quiet life" it is also funny that this is again a point in which disagreeing with him is beneficial. He wants to return home to Waterdeep because he is more comfortable there, it is the easier route for him. He is more happy though, if you take him adventuring (or to Baldur's Gate) and thanks you for encouraging him to leave home. Not that he is unhappy in WD but there is a discernible shift in mood and tone between the WD and the not WD endings.
