Peter Benoit returns in ‘A Million Little Things’ Season 4 Episode 16

The A Million Little Things Season 4 Episode 16 begins with a celebratory dinner. They celebrate Maggie and Gary moving in together and Eddie’s autograph signing the next day. Then, Anna secretly grabs a shot at the bar and runs into an old friend, Carly (Robyn Ross). Anna finds out that her friend is dating her ex-husband, Peter Benoit. She can’t believe that Carly would date Peter after hearing Sophie’s testimony on Maggie’s podcast. 

Anna has an outburst, and Gary suggests Peter leave. However, Peter refuses. Instead, Peter points out that Gary looks familiar (Viewers should recall that Gary and Christopher attacked Peter). Gary responds by threatening him, and the group of four decide to leave. When Eddie drops Anna off at her house, she insists that he doesn’t need to stay with her. However, when she walks away, viewers can tell the run-in with Peter is still on her mind.

Eddie answered his phone excitedly during dinner about Charlie’s first day of preschool. However, she’s still sleeping, and he doesn’t get to talk to his daughter. There’s still no mention of Delilah Dixon (Stephanie Szostak) returning from France.

Meanwhile, Tyrell finds out he was not accepted to his fallback school, the University of Southern California. After a pep talk, Tyrell finds out that he was accepted into Yale University and thanks Rome for being an amazing father. Then Rome returns Dre’s call and takes the teaching job.

Meanwhile, Regina and Valerie (Andrea Navedo) lose a catering job because Valerie made a mistake, forgetting a gluten-free allergy. She insists that Regina should find someone else. However, Regina explains that she would rather have someone she trusts. The two end up selling all of the food they made out of the truck. Instead of a catering business, did they become a genuine food truck vendor?
