Did anyone else notice that Aaron seemed especially at peace in Sun's arms in this episode? While in Sawyer and Kate's arms Aaron was often seen to be crying, but in Sun's arms he seemed to be quite content. He even seemed to be looking at Sun with adoration.
My new theory...Sun's supposed to raise Aaron. Not Jack, not Kate....Sun.

Claire's suppose to raise Aaron, it's been stated quiet clearly. I think Aaron just got sick and tired of screaming for hours and hours, he's only little. We've seen Sun looking after Aaron in 'Maternity Leave' and he was screaming quiet loud when Claire left him with her.

btw, meant it as more of a joke than an actual theory. sorry.
