Well, of course, last week we saw (or you saw-I didn't get to watch till last night) the finale of This is Us! There are so many theories rolling around as to what's happened, what's going on, how we got to where we are in the present. Well, over the weekend, the cast of This is Us did a panel discussion on the show at PaleyFest. Watch what they think is happening! It's pretty funny and touching as well!
