Finn was hiding. In the Haunted Mansion.
He would either die here from ghosts or from. . . the professor.
He almost welcomed death.
The mansion was offering a deal to be 1000th ghost and to live there forever. He couldn't risk being a ghost and stuck hearing from Philby for the rest of his life.
He had to hold onto hope.
"Hey, Finn, did you run off somewhere or were you, like, captured? Because honestly, I wouldn't be surprised with the latter. I don't want to have to save you every two seconds," Philby said into the void.
Finn could have said something. Let Philby know he's alright.
He texted him.
Hey, man, I went to Pirates of the Caribbean. Finn typed.
"Oh, thank goodness," Philby said aloud. Finn could hear him leave the room.
Finn stood up. He got a text message.
I see you standing there, you idiot.
Finn thought to himself: I think he knows.
Lyk this if hE knows EvEry TiMe.
