By webbing the shit out of the wood pieces like so, you can squeeze through the gap to skip the 30 second opening cutscene.

First, laser the boyfriend into the pit so he can't start the cutscene. You want to web the bottom wood ~50 times. Once it's relatively open, try to squeeze through. If you can't quite get through, web the top wood towards the right towards the exit, and you should make it through.

I got through the exit at ~:40, whereas normally it takes ~:57 with the cutscene. Done fast, you can get through at ~:32-:33
