Hi, in order to gain access to Mortimer, wiki i have to complete Secrets Revealed? But that is part of a quest chain, i can't trigger just this part of the chain. so i backtracked in the quests involved, and as per wiki, i end up at the start of The New Arrivals.

My question is, is there really no way to start somewhere later, as close as possible to Secrets Revealed. i'm trying to leave as much of the main quest undone as possible.

In your answer assume

-i'm over Level 50

-just walked out of Vault76

-haven't even spoken to Pennington yet.

Thanks in advance.
