This week,9-1-1: Lone Starwasfull of reunions.

Still, there was much more history to play between Chad and Rob.

To get to do that with my brother….

Looking into his eyes, I could see him as the history that we have together.

It was so full that I really didn’t have to do that much for internal acting work.

I just needed to be present and look in his eyes.

And he is really an incredible actor to work with.

Afterhelming two prior episodes of the first-responder drama, Lowe is currently directing next week’s episode.

“And the Judd and Wyatt [storyline] is really touching, their relationship expands.

It was just really something to behold.”

That’s saying a lot, given this show has given us a lava rock death.
