Lindsay_Montana, thank you for the pics, I had no idea Melina had a daughter. I have always though she had just two sons. I have no idea where I get this 
Yeah, flashbacks about Mac and Stella's first date, or even just earlier would be cool. Not being shippy in any way, but it's obvious that they do have a great relationship and are great friends, that would always be there for each other 

 So yeah, IMO, that would be a good scene. I'm all for it, if they decided to show us. Anything on their background and past (recent or not) is always good for me 
By the way, I saw today another episode of "Providence" (well, a bit of it), and besides the fact that I was noticing everything in her acting and her expressions, it just seemed to me that she wasn't that skinny as she appears on CSI. Maybe (ok, probably) it was just my impression, or the angle and the way they filmed that scene
