Dudes!
I was on a different blog that was sidetracked on talking about ME3, the conversation got to talking about shepards kids, but how that would be impossible...well, i was thinking about it last night, and i thought, "dude! Mordin is a genetic scientist, right? So, he can manufacture a way for Tali or any other alien that has the hots for a human that allows them to naturally have hybrid children!"
Anyway, that's my take on it...what about you guys?
