The Walking Dead season 7 episode 15: The character Rosita saw at the end of episode 14 revealed

*Spoilers for The Walking Dead season 7 episode 15 follow*

Last week's episode of The Walking Dead ended in mysterious form when Rosita (Christian Serratos) sees a shrouded long-haired figure stood in the shadows holding a crossbow leading viewers to believe initially that Daryl (Norman Reedus) has come to help her in her mission to assassinate Negan (Jeffrey Dean Morgan).

Upon second thoughts, however, it became clear that this character could, in fact, be Dwight (Austin Amelio), Negan's former right-hand man who has been on the cusp of betrayal for weeks now.

Loh and behold, the show's latest episode proved it was Dwight; Rosita brings him back to Alexandria and, locking him in the prison, fills Rick (Andrew Lincoln) in on the development. The outing ends with Rick - suspicous as ever - holding a gun on Dwight, ordering him to get onto his knees.

The moment arrived immediately after a plot twist that saw Sasha lock Rosita out of the Sanctuary as she ran fully armed directly into the heart of The Saviours' compound fully prepared to die in combat avenging the death of Abraham (Michael Cudlitz).

It's revealed in latest episode 'Something They Need' that Sasha survives the moment, but is caught and imprisoned by The Saviours where she attempts to acquire poison from Eugene in a bid to commit suicide.

The Walking Dead ais in the UK tonight (27 March) at 9pm on FOX.
