Exhibit A:

That time she barges in on Picard and Vash’s breakfast date knowing it would catch Picard off guard and make him lose his shit and THEN she proceeds to flirt with and actually STEAL his girlfriend lmaoooo

Plus in the same ep, the time when Worf looks at Vash and says "Nice legs ... for a human" and then Beverly ogles Vash as she walks away and then does a double take to check out her legs and wasn’t subtle about it at all!!!

Bev x Picard x Vash totally happened that night!

Exhibit B:

Let’s not forget that THIS was her reaction to seeing THEE Lwaxana Troi in all her nude glory. She simply doesn’t know what to do with herself! I believe this is what they call “gay panic” lololol Couldn’t be more obvious that Bev loves hot women as much as she loves her man Picard. Yes Bev, don’t suppress your feelings!

Exhibit C:

And finally there’s this ... wherein her reaction to having her wrist so lovingly kissed by her former male lover in a new female body makes her pause and consider “Hmmm am I really straight? Probably not”. I like to think of this as when she was in her early baby bi days, coming to terms with her sexuality and challenging all her beliefs about herself and about love <3

Not to mention all the tenderness she shows to the women in her life, the touches, the caresses, the knowing looks and soft smiles. The signs are all there. So.
