It all depends.
Are the 2 of you living together now? If so, then there might be concern...or not.
If she lives alone currently or with another person or a group of persons, then less likely to be a concern...or it could be a foreshadowing of her future plans...or not.
In any event, talk to her, she's the only one who can supply you with an answer.
By the way will all her parts be bionic or just her lesbian tendencies?
