5 Shepards ( i know, what a waste of time that ended up being)
Female Shepard, went for Liara in ME1, liked her naive and awkwardness... and Kaidan was boring as hell. Stayed loyal to her, thou somewhat disappointed with her change of personality.
Female Shepard, Kaidan in ME1, went for Jacob in ME2, was going to go for someone else on ME3, she just uses them and discards them XD.
Female Shepard, Kaidan on the first one, but since Garrus was finnaly available and Kaidan was a moron on ME2, went for Garrus, was going to stay with Garrus on ME3.
Female Shepard, No one, she doesnt need anyone.
Male Shepard, this dude was created solely for Tali, so he went single on ME1 and was going to go loyal in ME3.
What a freaking waste of time.
