Corrected entry: When Eggsy visits Galahad in the hospital (first time you see Galahad awake after the coma) Merlin comes in to show Harry the replay of the professor's head exploding. Then they watch Valentine's "free Sim cards for everyone" conference and Harry notices that Gazelle also has a scar on her neck. Close to the end of the film, when Merlin blows up everyone's heads, Gazelle should have too. (00:41:50 - 00:44:00)

Correction: That's not Gazelle - it's another brunette assistant.
