I like the idea of a Vulcan character who constantly does very reckless things so her human crewmates think she's strange but then she always has a logical explanation she delivers with absolute confidence.
"No, it was perfectly logical for me to jump out of the shuttle at that time. I had a breathing apparatus, and I was certain I could seal the subspace rift by hand before the Romulans opened fire. This was the only solution that would result in zero casualties. I might have died, but giving up is illogical."
She's known as one of the most fearless members of the crew.
Other Vulcans try not to acknowledge her.
