We've hinted for some time at a rough patch on the way for Mark and Lexie. But here's another piece of the puzzle courtesy of Michael Ausiello of Entertainment Weekly.

See what you make of this item ...

Q: I love Grey’s Anatomy but what’s this I hear about trouble on the horizon for Mark and Lexie? Who is this supposed mystery woman from Mark’s past?

A: From what I've gathered thus far, I believe she hails from Terminator: Sarah Connor Chronicles and has McSteamy DNA coursing through her veins.

Thoughts? Theories? Share!

mcsteamy's daughter!!! that mcbastard! all that man-whoring leads to a kid! we wanted a mcbaby, but mcsteamy's baby? seriously? seriously?


She is so his daughter ! I mean think about it .The girl who is playing her is only 19 so that rules out her being his mother .This post rules out her being his ex . And I don't think its his sister because ,just like a lot of you have said already , how in the world would that cause a rift between lexie and mark ? Now a daughter on the other hand would ! I hope we get a little more info on this storyline soon because it has so got me hooked!


I think it is his daughter too, I mean, none of the other possibilities would really cause trouble for Mark and Lexie or work with the actress the´ve chosen. I truly think it is a good plot for Mark and Lexie, besides, you know, troubles mean more sreen time lol And it would definetly be a problem, because Lexie and especially Mark are both so concious of their relationship. I just hope they stay together in the end. Slexie should be forever.


maybe that actress is 19, but she looks like older, I don't know, maybe it's the make up, I don't want a daughter but If it is a daughter, I don't like the casting, it's a horrible mistake sorry for my english


I don't think she is his sister. And if she is really his sister.. what problems can it cause him with Lexie?!
I have a feeling it will be his daughter!!


The actress is only 19 so it's definitely NOT his mom. They had a casting call for a character named Riley who was 18 and kind of trashy. My guess is, the actress Leven Rambin will be playing Riley and she'll be his daughter. Should be interesting! Her and Lexie would be only 6 years apart. I just hope they stay together through this. I love Mark and Lexie!


Please, I really need her to be his sister.
Not his daughter please. Just..let her be his SISTER , pleease :)
Btw.. Isn't he gorgeous in this pic?? Love him!


what if this mystery woman causes mark to break little grey's heart?


Whoever it is, the character is going to be played by Leven Rambin, for those who didn't know.


well a wike wouln't share his dna so is his daughteror his mom he is a only child
