Sam is?

At first, when I saw the pic, I thought Sam had stolen it from the home because he wanted to replace Andrew or something but my dad came up with a thought like 'Well what if Rex was just a tee-ball coach or basketball coach when they were little and he just had a picture of him with the kids or something...?' so I kind of thought about that. I just don't really think that he's related to anyone. Maybe they're going to use Orson's original storyline on Sam and have him get close to Bree before stealing her business and all of her money...?

I almost chose Other, because I am pretty sure he is an alien robot from outer space looking for another body in which to store his consciousness...I mean, who wouldn't want Bree's body? But I chose not related to anyone on the Lane...just guessing, but it seems like it would be easy for Sam to fake being related to Rex, since there's no one left alive to deny it (Rex and the mom are dead) and Bree is so ready to accept him, and Sam didn't know Rex so Bree has no questions to ask Sam that he could get wrong about his father...hmmmmm!
