Some things..
Peters power is unknown right now. Obviously its not the same as before where he absorbs them like a sponge when he is around others, but he also does not steal powers like his dad did. We know this because he touched mohinder to get his power, and then used the super strength to break free and get the soldiers. Once he froze a hole into the plane, mohinder was out of his chair and helped peter not be sucked out of the plane. Obviously mohinder coudldnt have done that without super strength. It is likely that peter can now only hold 1 power at a time, but we wont know till later.

[Show spoiler]is not on the plane, they showed a clip from the next episode on nbc where ando and the fast runner get together to rescue hiro and parkman.
Also, at the scene where peter injects himself at the end of chapter 3, you see him run up to his brother, touch him, then fly out the window. So there is still continuity going on.
Ive read that there is going to be an entire episode dedicated to ali larters characters... sucky..
Looking so forward to monday!!
