The Tower (Once Upon a Time)
As he arrives back to the apartment, Zelena is making tea for the Charmings, but David is very suspicious about Zelena, even after Mary Margaret tells him that Zelena was once friends with her late nanny Johanna. Unbeknownst to the two, Zelena is spiking one of the teas with the nightroot and after she returns to join in the conversation, Zelena asks David if he has any fears about Mary Margaret's pregnancy. David says no and takes a drink from the cup with the nightroot. As David later leaves the apartment and drives off, he begins to feel unnerved after he sees what appears to be a hooded individual in the road and texts Emma that he might have seen the Witch.
