I don't know...honestly I wouldn't object to a marriage/engagement...but it's not a requirement IMO...I'm sort of on the fence about it...all I really want to see is some sort of satisfying conclusion for Kaidan/Femshep's relationship that sort of solidifies their intentions to be together and continue to meander around the galaxy, making lots of love and putting fear into the hearts of those who would threaten the good citizens of the galaxy...
In regards to seeing Kaidan do some "saving".....yeah I wouldn't mind seeing that...even if it's something on a relatively small scale (like someone mentioned having him biotically push away husks intent on getting Shep), or maybe having him push her out of the way of a hail of gunfire, land on top of her and have another one of those "faces really close/almost kiss" moments that we saw in the first game....of which are almost as sexy as the actual love scenes...
I'm glad to hear that I'm not the only one who has sat here wondering how Kaidan would react to the new crew...I think Jack's "bluntnesss" would put him off at first, but once they started talking to each other, they'd likely get along well...as has been said, they do have quite a bit in common.
Yeah, I think Kaidan may feel somewhat of a kinship with Jacob, but there'll be some hearty distrust there due to the cerberus angle, as there would be with Miranda...
Garrus, Tali, Dr. Chakwas, Joker would be a comfort to him methinks, old familiar faces and people that he both liked and respected...and with Kaidan around, you know Joker is going to comment..."wow, now it REALLY is like old times"...
Thane, yah as has been said I do agree that Kaidan would likely have some issues with Thane's philosophy regarding killing, but I also think that Thane's calm and collected personality would eventually win him over...
I'm not sure about Samara...Grunt, I think he'd be amused by...
Ah...now on the flip side, what do you think the new crew members would think of Kaidan?
