Promise I will fill this in when I am more awake, just wanted to mention Sam's line to Merrin in Learning Curve about the fun/cool stuff she did in her life not happening until she was 15, and then Merrin asks what stuff and Sam's all "Just... stuff", which I took to mean Sam was at least experimenting sexually quite young perhaps in rebellion to her military father yadda yadda *yawn* totes not a virgin. :P
