I'm totally hoping that the last LI will be Blackwall, and though I haven't really had much hope about him in the past, I have been getting a good feeling about him these past few days. It's a combination of factors:
- if Viv was the last LI, all of the female companions/advisors would be LIs (Leliana was in DAO), and that could send a weird message, that every woman is up for banging you
- Viv is, like many here have laready said, probably the most likely to be race-gated, and if it's true that one of the already announced ones is, then Solas means she's not in
- the mention on a PAX panel the other day about Blackwall being something for those who did not get to be with Duncan (I know they tried to explain it away, but they also tried to explain Solas away and look where we are with him)
So, yeah, I think Blackwall will get the last spot. If he does, I would go ahead and say that the last race-gated LI will be Cullen, because then we have five male LIs and only three female LIs, so it would work out quite well - three of each gender that are not race-gated, and an additional two males who are race-gated.
As to Blackwall's sexuality, I'm hoping that he'll be bi. I personally plan to romance him with a femquisitor, but I totally approve of the bara crowd getting a go at him to. I might even romance him two times, once with a femquizzy and once with a male.
Sorry for the long post, btw...
