I'm such a dork for these two.
This was inspired by Shepard's comment during the Samara mission when he asked Kaidan if he could learn to biotic float, to which Kaidan replied "Not in the next ten minutes."
Though I’m not crazy about the ending to Mass Effect 3, it at least leaves things open enough for each person to craft their own story of what happens after the war. In my mind Shepard would take a few years off from active duty to recover from his injuries and probably retire from the alliance. But being the workaholic that he is he’d eventually return to his role as a council spectre. Luckily, he’s still got Kaidan to remind him to take it easy every once in awhile.
As for Kaidan he’d continue to teach a class of biotic students as well as resume his own spectre duties. With the citadel being so close to earth he’d be able to easily serve both the alliance and council. Plus without the impending threat of a reaper invasion he’d have more time to improve his biotics and finally master that tricky biotic floating thing.
Sorry I haven’t been posting art lately, been super busy with work this month, hopefully things will slow down in January.
