But there's an even deeper level to the "Reacher" easter egg iceberg — a level no fan was even aware existed. I'm talking about the Trish level. Yes, "Reacher" has featured a secret character since its second season, and nobody except the production design team knew about it. Goshtasbpour revealed how she and the set decorators create backstories for the unseen characters of "Reacher." Trish first "appeared" (without actually appearing) in "Reacher" Season 2, returned for Season 3, and now, she's back once again for Season 4.
