Re: Mass effect 2 Romance glitch
I don't think that it was ever intended to have a romance or another romance after the suicide mission.
The romance must be locked in before you hit the Omega 4 relay and the romance scene is triggered if you hit it.
That is a hardcoded event that determines your romance for this playthrough.
You can only have one full romance, (Kelly or Samara are not full romances), in one playthrough.
