Dammit. I seriously asked for help 3 pages back. Stuck and can't get out of one of those goddamn free roams (I HATE them!!!) It's the one in the DIK mansion. Phone tasks says to "chat with people" but did with everyone in the house and even tried chatting on the phone to no avail. Ep 4 or 5. One where "father" is the only one still clickable and says "leave me alone maggot..."
But no help and 2-3 pages of shit posts about retarded fan theories.
It would help to describe more specifically which free roam you're in; there's more than one in the DIK mansion. It sounds like this is the one in Episode 4, after spin the dildo was interrupted by the Cathy cluck. [EDIT: Ah, I was correct, you are in the Episode 4 one.]
If that is the case, you need to talk to all the DIKs to proceed: Jamie and Leon, Nick, John Boy, Jacob, Tommy, and Rusty. Once you've spoken to them all Quinn will appear next to Tommy, and talking to them will end the free roam. (You can also talk to Riona, Mona, Heather and Melanie and Sarah, but they do not seem to be necessary.) If you figure out which DIK you are missing we can try to point you to them.
As far as general advice, it's important to understand that the arrows in free roams are
EXTREMELY confusing: your orientation in a new room does not match the facing from the previous room, so often an arrow pointing 'backwards' will take you to a different room than you entered from. Also, there are occasionally multiple arrows that seem to point in the same direction and it's easy conflate them in your mind without realizing they are separate options.
