I'm trying to ally the White Glove Society with the Legion for part of "Render Unto Caesar". Having never taken this path before, I think I hozed it somewhere along the line, but I can't figure out where.

I talked to Marjorie, then Mortimer, and followed all of the dialog options. I ended up killing Ted Gunderson and framing his dad for it. Mortimer says that the banquet went swimmingly well, but there seems to be nowhere to follow up on the alliance question. Marjorie seems to have disappeared, but the quest pointer is still pointing at Mortimer. Caesar has nothing new to add and I'm getting nowhere. Any suggestions (reverting to an earlier save is an option, but I'd rather not).

Thanks.

You do need to talk to Majorie again after the banquet to get her to side with Caesar, I know it took a few hours after the 7pm banquet before she left the locked white glove society room where the banquet was held. Maybe try waiting a bit and coming back and looking for her.

I just did this one. Easiest thing is go to sleep at your suite (either over at the Tops or the Lucky) and go back - she'll be there the next morning.

you can also get your own suit at the Ultra-Luxe
