Two weeks later, and we're still not over This Is Us' latest twist. (Warning, spoilers ahead!) In the final moments of the NBC hit drama's second episode, Randall's (Sterling K. Brown) kids excitedly greet "grandma and grandpa" at the door. Grandma? It's Rebecca (Mandy Moore). But grandpa? No, it wasn't Jack (Milo Ventimiglia). It was Miguel (Jon Huerta), Jack's BFF we were introduced to in the Jack-Rebecca storyline, set in the '80s when The Big Three are 8 years-old. Say whaaa?! Has Jack died? Did they get divorced? What is happening?!
"I do know why Jack wasn't walking through that door," Milo Ventimiglia told E! News' Sibley Scoles after the second episode shocker. Of course, he's not going to share that precious info with us.
"Just wait!" Milo said. "Just wait. This is old-fashioned television story. You gotta wait. Appointment TV!"
In the second episode, we see Jack and Rebecca going through a rough patch, with Jack turning to alcohol to avoid addressing struggles at home. By episode's end, Rebecca had delivered a powerful "Fix it" speech (Mandy Moore FTW!), and it seemed like the couple may be OK. But Milo warned fans that they will continue to see the highs and lows.
"We're going to see a couple in their high moments and then also in their low moments," he explained. "So the fact that it's present day and Jack is not grandpa, that's looking in the distance and being like, oh, I see where I'm going but I can't quite see the road around the mountain. You're going to find out, you're going to learn about it."
As for how the heck Miguel ended up being grandpa to Randall's children? Milo teased, "It's to be discovered." To hear more from Milo on This Is Us' big twists, press play on the video above.
