Hello there!

Might be a spoiler but i couldn't figure it out. I could climb out of the window but when i try to move to the next one Cath pretends to fall of the train and after that the only option is to climb back into the cabin. Am i missing something?

Best regards,
Mate

Was it your compartment you climbed out from?

I've experienced the same from mine and from the other one in the first car (where's the blue luggage.

You can't move across to the next compartment from your own compartment window, because the guy next to you (Alexei Dolnikov) has his window closed.

However, later in the game Anna Wolff in compartment F leaves her window open, meaning you can climb across from the adjacent one (with the French and English woman).

Hint: It's during the concert. Also, Anna Wolff is Hungarian.
