with the amount of PTs I've done and plan to do prior and post ME3, seriously I'll try to cover a lot of ground, renegade Kaidan is one of them;
I might also play femShep again and eventually try all the romances once, though perhaps not all the variations of loyal versus cheating ...
did we ever bring up what might have happened if Kaidan actually was part of your squad in ME2?
What would his loyalty mission be? I believe him if he says he's over his ancient history (so no finding Vyrnus' son and apologizing or finding Rhana and afterwards you have to hold Kaidan's hand because he's so depressed ...

) ... so ...
I wish it was something normal ... like visiting his family on Earth for dinner, just because he wanted to see them one last time before a potential suicide mission or something
of course that would cement the 'boring' label because what is a loyalty mission if a.) your sqiaddie doesn't *really* need you to solve their family issues and b.) there probably won't be any shooting
