I went with her to alot different places to trigger the quest, but it wont

. I am level 32 btw, already finished the game 2 times etc. So alot of the dialogue triggers with different people dont work for me, Cause they only say some things once. So the only triggers now are visiting Camp MCarran and some others. But it dont work
Maybe finish some quests with her? or is it a bug?
Someone have any ideas?
