Yes, we finally know who is the mother of his son(and the other surprise is that it was twins! lol) but yeah, we still don't know if they are together, or not.

We also know why Kevin and Randall were not speaking to each other for a while.

The other big surprise was that Toby wanted another child, and that they adopted. It should not be a surprise, considering that there was a few adoption already, but I really did not see that coming! lol

for a moment i thought they will name their baby rebecca
I thought the same, because they showed a scene with Rebecca before Jack said the name, but I prefer that, it's gets weird when many people in the family have the same name, he already had the name of his grandfather.

Seeing the dotors of the Big Three was so great, I missed him :)

That was a nice season finale, no cliffhanger, and a lot of answers.
