Characters/Pairings: Fifth Doctor/Tegan, Nyssa
Recced because: I couldn't end the week without reccing something for one of my long-time favorite pairings. This story is a guilty pleasure of mine. Nyssa and Tegan have to take care of an incapacitated Doctor in this one, giving both the opportunity to use their respective skills. I love the meaty plot and the slow build-up to romance.
