Sil: 

This is a real tough one.

A little off-topic but Splice was such a messed up movie dude.

I think the topic should be "who would you rather sleep with" because I choose both. But overall, Sil seems more the fighting type with intelligence.

Good fight...I'm gonna go with Sil, she seemed stronger and more willing to kill. ill take her in both.
