Edinburgh army Squad E grenadier, age 32. So mathematically minded that he ascribes almost everything to formulae. Stubbornly logical.
A former math professor. He didn't consider himself that attached to the school, but he still hangs onto an old photo of him and his students.
Though he didn't put much stock in "willpower", he find new perspective in teaching Hanna. Surprisingly, he comes to enjoy her unpredictability.
Baffled by Hanna's affection for him, he finally gives in, and they marry. Her confession had caught many by surprise but none moreso than him.
