One replays the moment from the end of Toy Story 3 where Andy gave his toys to Bonnie, but the other shows a scene of an even younger Andy playing with his toys.
What’s potentially more interesting than some of the movie’s new friends, is the return of a very special old one.
The trailer contains a pair of flashback sequences that show Andy once again.
It’s hard to tell if this part of a significant flashback sequence in Toy Story 4, but if it is, we might get to actually see some earlier events in the story that we never saw, like the loss of Bo Peep.
