I just think they are because they have a lot of similarities (facial, hair color, etc). That's why I put possibly.

The thing with it is the shows weren't originally made to be in the same universe, so it wasn't planned ahead of time I feel like it was added later. The best explaination I can give is that because it's an alternate reality from our own, history happened different. Ex: Cell phones we have no were out in the 90s. That's why they have them in 16 and why it's so far behind. Plus, even if the Emma's aren't the same, 6teen would still be about that time for Jen to babysit MacArthur.

Lastly, the episode titles aren't part of the episode. The season didn't even air in 2008, so that title has never made sense to me.

But like I said, it's just a theory, and since the shows weren't originally meant to co-exist (except for TD and RR), this is the best timeline I could come up with
