'This Is Us' Season 3 Episode 6 Air Date, Spoilers: Will the Show's Cast Like What They Find When They Unearth the Past?

“This Is Us” season 3 episode 6 looks to be shaking things up with an episode focused on the Pearson children yet somehow still showing Jack's (Milo Ventimiglia) past. But with all the challenges that Kate (Chrissy Metz), Kevin (Justin Hartley), and Randall (Sterling K. Brown) have already gone through in their lives, it looks like Jack's past may add to their experiences even beyond their father's grave.

The “This Is Us” season 3 episode 6 synopsis is short and straight to the point. Fans can expect Kate to deal with Toby's (Chris Sullivan) depressive condition during the episode. For the other Pearson siblings, Kevin has apparently become obsessed with a part of Jack's past, which Randall will hopefully help him sort through.

The “This Is Us” season 3 episode 6 preview trailer provides more details for fans who are unsatisfied by how short the synopsis for the upcoming episode is. Fans will notice that the preview trailer mentions Vietnam to be an important part of Jack's past. Of particular note is the reason for Kevin's interest – a necklace given to Kevin by Jack which belonged to a woman in an old picture – in Jack's time in Vietnam.

Kate gets her own moment when the “This Is Us” season 3 episode 6 preview trailer gives fans a glimpse of how hard depression has hit Toby, but the exact reason for his current state is not hinted at. Randall also gets some additional plot depth, with his wife, Beth (Susan Kelechi Watson), seemingly going through a significant amount of stress in the upcoming episode.

With Kevin's obsession over Jack's past in Vietnam being the “This Is Us” season 3 episode 6 plot hook with the most teaser information, fans may wonder what exactly Kevin will discover about the Pearson children's father should he decide to explore the past in person. Potentially, it could be as mundane as meeting a person who was important to Jack during his time in Vietnam – which does not even have to be romantic – or as extreme as discovering that the Pearson children have another sibling overseas.

Fans looking forward to unraveling Jack's past and Toby's depression can catch “This is Us” season 3 episode 6 when it airs during its usual Tuesday broadcast schedule tonight, Oct. 30. Hopefully, the secrets that are discovered in the upcoming episode help the Pearsons understand the lives of their loved ones better.
