Hi all!

OK. The last scene.
After Jane disappears from camera, we can see a man (who some people think its Partridge) and a girl on a fun slide.

Now, the slide is DINOSAUR shaped.
Earlier, Jane was talking to lisbon that Birds are like MINI-DINOSAURS... so there is metaphor that the man beside the slide is a man who loves birds (pigeons), just like...

so I think to things:
At this slide it was red john.
He has a daughter.

Cheers!
