Can other investigators use Patrice's Research Materials in the same manner as one of her clues?
Thus could Silas use three of Patrice's clues to complete his personal story and could one of them be Research Materials?
I don't have all the expansions but I think I have heard tales of two gates being opened by a single mythos card (?) but if so let's hypothetically say there are four investigators playing a game with six gates already open when this double gate card appears. If Mandy was using her Personnal story and there were already 4 clues on her PS card and there were 5 Elder Signs on the board and the first Gate of the Mythos card appeared at a sealed gate location (thus completing Mandy's PS) but the other gate opening appeared at a non-sealed location (thus immediately awakening the AO) then would Mandy be able to seal it--or let's say even a different open gate on the board--and have the investigators immediately win. Or does the AO awaken first?
A lot of "ifs" I know, but seems like a potential timing conflict. Course if there are no such double gate cards the as Gilder Radner on SNL used to say "Nevermind"!
