Jack

To say that the Savior of the Galaxy and biggest hero in it would find herself in a relationship with the crazy biotic criminal turned teacher was a surprise was like saying the Reapers were a mild annoyance.

But that is exactly what happened after the war.

Shepard was finally cleared from her stay in the hospital when she found Jack at her place.

The next thing she knew they were both naked and having some of the most passionate and nearly violent sex she had ever had.

The funniest part was when it was done Jack asked her to dinner.

So that was the start of a very unusual relationship but Jack and Shepard made it work. Even if Jack was adamant about making Janes ass as red as her hair most nights.
