Maybe Shepard was all serious at the moment, but that's what I said the first time I heard it, lol
I feel like the writing for Shepard was always a little too stiff, more so if you play Paragon. I always apreciated the times when Shepard could crack a joke or, you know, act like he had emotions.
Best part was after recruting Archangel when Garrus asks how bad his injurys are and Shepard replys:
"Hell Garrus, you were always ugly. Slap some face paint on that and no one will ever know the difference."
It's a little off topic, but I never did care for Male Shepard's voice acting. It sounds so phoned in at time, even more so if compaired to female Shepards.
