SkyGem Speaks

When asgard 6 were in new york, playdon said in one of his lessons that there had been a series of fires in the city - which ended up being the firestorm that caused the alliance to leave new york

At some point in the main trilogy (i'm like 90% sure it was during jarra's eden dig site tour) she points out a blue flying lizard from danae and explains that no one knows any more why it had been brought to earth - they were brought to keep the falling star population in check

jarra's aunt, seanna tell morrath, was likely named after sean donnelly!!!

There's a scene at the end of the drago 2781 sequence where drago and jaxon have a meeting with clan leader justina. I don't remember the scene very well because i've only read that series once and i didn't have any idea what it was referring to at the time, but they meet somewhere in new york, and they read a plaque that talks about the barricades, and the fights between the people in the settlement, and the scavengers of new york. Iirc drago makes a joke about taking over the nearby settlement in honour of their ancestors.

I love how deep and complex the lore is in this series!

The other 50% of the time it's the autism, and the joke really has flown over my head

Both would be cute, but either way the one scene i can't get out of my mind is raven (who already knows who she is because of the solar 5 rescue) introduces himself to jarra with his full name and jarra, who's only ever known him as "raven", sees the way he's looking at her, his expression so full of fondness, and the only thing she can think to ask is, "My Raven?"
