5.9 The Cell Another masterstroke was to include Damon in said mystery, and this week went one step further by having him still be directly involved in the present-day goings on. The Cell was essentially a standard flashback episode that served, as always, to introduce a new character and explain their relationship with one or more of the Salvatores – this time Enzo, who was an Augustine prisoner at the same time as Damon and has probably been cooking up his own crazy revenge mission since the 1950s. While we were revisiting the past, Damon was explaining the previously unknown chapter of his life to the also-trapped Elena. We find out that, after being sold to the Augustines by one of his family in the 50s, Damon was experimented on for five years alongside Enzo and, after deciding that one of them should take the other’s food in order to build up strength and escape, Damon killed the Whitmores and essentially left Enzo to die in captivity. The torture scenes were graphic enough to please fans who like that sort of thing, but these flashbacks were for two things – making us like and feel sorry for Enzo and providing a reason for Elena and Damon to break up in a future episode. Meanwhile, Caroline and Katherine had their own little adventure as they attempted to help Stefan with his PTSD. Any episode with Caroline and Stefan sharing scenes is a good one in my book, even if her plan to lock him back in the box was a pretty dumb one. It all led to Katherine locking herself in there with him and talking him through his not-well-hidden issues with Elena leaving him and, when they came out of it, sparks were most definitely flying. Most of us called it last week – with Elena off with the other brother, Stefan could still fulfil his Doppelganger needs with Katherine. Some of us have been waiting for this for a while. It’ll at least give her a reason to go on living, and that lends some urgency to her quest to stop the ageing process. Will the solution have something to with Nadia? Probably but, as Katherine is currently hiding out from the travellers, asking her for help might be a bit tricky. A more pressing matter is whatever’s going to happen to Elena next week, as while Damon was out from the bullet Aaron quite justifiably put in his head, she was taken up to the lab and introduced to Enzo. God only knows how his mental state is after 70-years in that basement cage. See you next week for mid-season finale shenanigans! Follow our Twitter feed for faster news and bad jokes right here.
