 Malachy later witnessed Mercedes and Calvin kissing but did not interrupt them. Wallace felt this was because he truly loved Mercedes and had accepted that "his life is much better with Mercedes in it". Whittle explained that Malachy tested Mercedes and Calvin because he wanted to discover if "what he saw was a one-off or more serious". The pair failed the test and Mercedes, fearing that Malachy knew the truth, told Calvin that they had to end their affair, "but they simply can 't stay away from each other". He added that the relationship could become more serious for Calvin as "he's in danger of really falling for her". Mercedes began to develop feelings for Calvin who did not expect Mercedes to develop "such deep feelings" for him. When Calvin rejected Mercedes she informed Calvin's sister Sasha Valentine (Nathalie Emmanuel) that Calvin left Sasha's then boyfriend Warren to die in a fire; Sasha responded to the revelation by throwing Calvin out of their home. Not being able to "get past what happened with Warren", Calvin and Carmel decide to end their relationship. Calvin confronted Mercedes, who "tells him that he's ruined her life and warns that she's going to do the same to him".
