"The Pitt" Season 2 finds Dennis Whitaker carrying himself differently. He's teaching. And, as Santos lets slip, he also has a "friend with farm benefits." It's a development that invites assumptions about what's fueling Whitaker's growing confidence — but according to Gerran Howell, that reading misses a more important point. He's no longer just learning — he's also teaching, and modeling himself after Dr. Robby, who has taken Huckleberry under his wing.
