I think you're over thinking this part of the story. The actual quote, after mistaking us for Azem, is, "He/She told me a falling star would appear before me, and I suppose you must be it. Truth be told, I did not expect the expression to be so...literal."

None of this says Azem saw the future and was being cryptic, nor was Azem avoiding us. It appears that Themis doesn't know how to go about investigating Pandaemonium and asked Azem for advice and Azem's advice was look for a falling star--in other words look to heavens for the answer or you'll figure it out when you get there. Azem was just being an encouraging friend, they didn't know the future, and this is pretty on point for the Ancient that can call their friends to their side.

Themis' line about the expression being literal is ironic because you fall out the sky the exact moment he sets out to investigate Pandaemonium.

This is all supposed to be a funny coincidence in the "meet cute" sort of way.
