I think Fiona is hilarious in that Michael's always having to hold her back. He's always making her use less C4 than she wants and she always pouts about it. (Not to mention that she can make it herself...)

I've run across one, maybe two fanfics that involved sex on a mission, and Sakura was wearing a regular bra. I'd rather have seen them have to deal with a sports bra, but then again I like seeing a little awkward in the sexy. It makes it more real.
