okay so i get to the jefferson memorial and kill all the super mutants in it and well i can't find my dad all i find are 7holotapes and a bunch of special objects i can't interact with ...


if i follow the helper arrow it leads me no where as there is absolutely nothing i can do in the rotunda... the rotunda is a small room and i've searched every inch of it....


so where do i go? how do i complete the rest of the quest scientific pursuits?

you need to listen to all of the tapes, one of them tells you the location of another vault you have to go to.

i found some of the holotapes in the gift shop area and some of them in the sub basement...

i found nothing in the pump control or the rotunda... is there a 5th area to find tapes in? the ones i have ... have no clues about anything at all... it seems like tape 4 if it exists might... but i haven't found it.. do i need to access from another door to the monument? like an underwater one?
