Doctor Leta, regardless of her Alteiran or Tyrian iteration, is very dedicated to her research and her job when she isn't out playing combat medic and will readily give you the look if you're keeping her from her work and wasting her time. If you combined the characters Steward Gixx, Prof. McGonagall, the Dean from Monsters U and Nurse Ratched you'd have a good approximation of Leta.

This was an attempt at a media experiment with pencil and ballpoint. I'm not sure how I like it honestly, I blame using flimsy paper that I thought could take it but apparently not so much. Maybe try again with a better surface next time.
