"Pure: Part 2" (Episode 7.04)

"Pure: Part 2" is the fourth episode of Series 7 and the 59th episode overall.

This episode primarily focuses on Cassie Ainsworth as a young adult, taking place around five years after she graduated from Roundview College.

It focuses on Cassie's attempts to deal with her family struggles (brought upon by her mother's death) in Wales, her relationship with her friend-with-benefits Jacob, and her newfound popularity as a model.

Plot
Jacob and Cassie go to Wales to visit her dad and brother. The last time we saw the Ainsworth family they were so blissfully happy that they forgot to notice their daughter was imploding in front of their eyes, but here it’s Cassie who has to compensate for her father’s fractured state. Ruben has been coping with an emotionally absent father since his mother passed away, and all Cassie can do is get frustrated with her dad for checking out.

The episode also explores in the exact nature of Cassie and Jacob’s relationship. Can you be friends with a guy without sleeping with him? Only if you’ve already slept with him previously, her flatmate tells her – and it starts to look as if she’s right.

Later, Cassie is approached by a modelling agency for some fashion work, and it’s the first time we’ve seen her truly happy. Contrasting with the impromptu night out with her flatmates in which she won’t even crack a smile, we start to see the old, carefree Cassie when she’s partying with her model friends. It's likely the viewer will never know whether she makes a huge success of herself, but one can be inclined to believe that her co-worker was right and that something great is just over the horizon.
