Did anyone else notice the differences between Olivia's memories and Peter's memories of the picnic? In Peter's (which we saw in the premiere), the picnic blanket was red and the shirt he was wearing was grey. In Olivia's, the blanket was green and Peter's shirt was brown. Think this is significant? I'd pick Olivia's memory over Peter's, as hers is photographic and the memory sequence was continuous, whereas Peter's was disjointed.
One mystery that didn't get solved though: where's Gene? Did Walter amber the cow as well?
