I think we can assume that Alice Eve won’t be playing a Klingon in the new Star Trek. Here she is, half out of her flight suit uniform and featuring a typically smooth forehead.
But that suit is the interesting thing. Trek Movie note that it’s the same as the one Spock is wearing, as well as one John Cho and Zoe Saldana were seen in a few months back.
he implication from this is that Alice Eve’s character is a member of Starfleet. Original reports stated that Eve’s character is new to the canon. TrekMovie hasn’t been able to confirm (or debunk) those reports, however many fans have conjectured she could be playing a familiar character. Guesses have included Yeoman Janice Rand, Nurse Christine Chapel, Lt. Marla Givers, Dr. Elizabeth Dehner, Dr. Carol Marcus, and others. Of that group all but Marcus were members of Starfleet. And if the outfit is indeed some kind of flight suit, that might not fit a nurse or doctor very well, but this is an alternative timeline so you never know.
They’re the Trek experts and I’m the one that just Wiki’d Marla Givers and Dr. Elizabether Dehner, so take their word for it, not mine.
