So there's a lot of information being referenced on this page, so here's a whole list of things you can look at for context:

Lyra saw Thistle's eyes glow back when they were fighting that frog monster thing here.

Thistle talks about Visions here.

And "Storms" should be a familiar term because they were referenced at the beginning of the chapter here.

Seems a bad time to mention that the next page is the end of the chapter...
