Who doesn't love to talk about the Pearson family?!
Well, this season it's getting a little bigger.
Michael Angarano will be playing Jack's younger brother, Nicky in season three.
All we know about Nicky is that Jack and him served in Vietnam together, but Nicky eventually died at war.
Creator Dan Fogelman teased that the upcoming season will explore Jack's time in Vietnam.
Angarano shared his excitement on Twitter writing "I am beyond grateful and very excited to be a part of this show, my grandmother even told her dentist."
'This Is Us' returns on September 25th.
Who is excited?! Loveeee this show!
