So interesting, isn't it? See, I totally see Rodney flailing left-handed because he's rolled onto his right side to smack Sheppard. I'm not sure about the baby, if that figured into it for me. Actually, it was probably that I knew what the hallway looked like in my mind and that Rodney would be sitting on the expanse of wall on the left, that John would have emerged from the right, and that I wanted John to see the baby's face, ergo: baby in left arm. Ah, the complexities of writerly thinking. Haha...
