There were originally plans for romance speech options and game endings for companions, but the idea was ultimately cancelled before any work was done on it. According to Jason Bergman (the Senior Producer for New Vegas), "Tt was clear that it wasn't going to be fun or interesting in any way. Also Avellone really hates romance in games."

One of the romance ideas that was talked about was if you romanced Cass, you were both going to get drunk and wake up married. And there was another idea where if your rep was high enough, the player would get married to their companion by the King, with him singing "Love Me Tender" a la Nicholas Cage in Wild at Heart.
