Although in her early thirties, Towers looks like she's been carrying the weight of the world on her shoulders for much longer. Everything about her seems to scream utility - tied back hair, no make-up, non-descript clothing in hard-wearing browns, sensible boots which won't break your ankle if you need to go running.

Her forehead is prematurely wrinkled with worry lines, her blue eyes are bagged and suspicious, and she's more likely as not to be scowling, so it's perhaps not surprising that she's given a wide berth by her colleagues and the general public.
