Story: Second Chances
Author: Lurky McLurklurk
Rating: All Ages
Word Count: 2182
Author's Summary: The Master's latest overcomplicated scheme backfires, giving the Fifth Doctor a unique opportunity.
Characters/Pairings: The Fifth Doctor, the Master (Delgado), Tegan Jovanka, Turlough
Warnings: None

Recced because: I may be a tad biased, as I asked for this story, but it's done so perfectly. The Fifth Doctor is able to confront the man the Master was, and it's as complicated, bittersweet, painful and wistful as you'd imagine. His plan to keep the Master this way is doomed, of course, and everyone knows it.

Tegan and Turlough, though they play supporting roles, are also characterised very well.

Author's Summary: Here, the manipulators and manipulated are one and the same.
Characters/Pairings: Fifth Doctor/Turlough, Tegan/Nyssa
Warnings: None

Recced because: I've always found Terminus an interesting story, and About-Face handles the aftermath brilliantly, from the points of view of Tegan and Turlough.

Tegan's reactions and Turlough's motives are deftly explored, and the Doctor is characterised perfectly, from his wry bickering with Tegan to his determined concern for Turlough.
