If Tali dies after being romanced, can you romance someone else?
I romanced Tali and locked it in in ME3, but she dies on Rannoch, so can I romance someone else in the game?
Solution 1:
No. Once a ME3 romance is "locked in," Shepard loses romance dialogue options with all other characters.
And since it must be said: it's pretty low of Shepard to destroy his girlfriend's species, no? Wanting to be Shepard's rebound after that incident is a death wish.
