ang dami kong tanong sa last episode. one was who was the other dr. carson and it's clarified nga na sa hilltop. the other is what's up with the frame up? and ano naman ang gusto ni Eugene bakit di pa nya tinulungan 'yung wives patayin si negan? ang gulo ng episode na to for me...
Other Dr. Carson is dead Dr. Carson's brother at Hilltop, and is also Maggie's OB-GYN.
As to why Dwight framed the doctor, I guess he didn't want Negan and the Saviors thinking that Sherry helped Daryl to escape, so he cut out the bottom portion of Sherry's letter to him, and planted it on the doctor to make it seem that Dr. Carson helped Daryl escape in order to impress Sherry.
Eugene is smart enough to realize that he has to get into Negan's good graces so he can help Rick from within--that little smirk on his face as he walked away from Negan says it all. Considering he just joined The Saviors, it's too early to get rid of Negan if he helped the wives, because if it backfires his position will be compromised.
And that last scene... I think Dwight and Eugene will form an alliance to help take down Negan.
