Just watching several Season 7 episodes again Initally, I thought her unexpected surprise appearance as Oswin in Asylum of the Daleks was such shocking & delightful addition that it set Clara up perfectly as a future traveling companion. Though, she had to share the screen almost equally with her co-stars here. Whereas in 'The Snowmen' she has more breadth to develop as she is introduced (& the Doctor is introduced to her) properly for the first time where, I think, we see such variety from Clara/Jenna. There's stern, funny, playful, sympathetic, friendly Clara aka Miss. Montague that is clearly popular with the locals
. For that reason, it's probably my pick of the series for Clara at her best (even if it wasn't technically modern-day Clara: well, she was & wasn't.... Should I leave it at that?). A close runner-up was her introduction proper in 'Bells of St. John' when the mystery of Clara deepened. You can often see how Clara's presence on board Tardis nudges the Doctor - however subtlly - towards a happier conclusion to the episode in spite of the chance involved in their meeting & the Doctor's emotional distance from her borne out of the mystery surrounding Clara. Just as a true companion does!
