The Character Romance thread (Official)

From what I've read from daveliam at this point it was only confirmed that scenes with Jaal, PeeBee, and a M/M mystery man was shown so far, the rest with Liam and cora was probably his speculation (unless he would like to reply and tell me that his leaks also included cora and liam). Like you said PeeBee being an asari it was a given that she'll be bi, but bear in mind that it's part of the lore for asari to be bi so I don't think she should necessarily take the bi female spot. Also, many females may not want to romance an Asari and having one as their only option for a squad romance would be kind lame for them so while it may be unlikely based on past mass effect female squadmates, I think Cora and Liam could definitely be bi just to give homosexual pcs a human romance option because not everyone wants to be stuck with an asari/just aliens (though I personally am looking forward to romancing PeeBee, and Cora in another playthrough, not sure if I'll play femRyder as I've never played a female shepard and just watched her romances on YouTube). But if Bioware does decide to not give f/f human squad/crew romance then that just leaves either vetra or a potential last squadmate. Of course there is always the possibility that bioware decided to make Vetra straight as well since the ladies got garrus in Mass Effect 2/3.
On the crew member romances, I think you are right that we'll probably have only two and I'm thinking it's Dr. Lexi (another asari) and a M/M (Reyes supposedly) so this would mean that when it comes to crew members F/F would not have any options outside asari unless bioware created a third crew member that can be romanced.
We don't have really any information on the romances that can happen outside the squad/crew so it's hard to say if they'll just be flings, but whether they are flings or not, they will likely not be of equal quality to the crew/squad romances.
