None of these felt deserving of their own post or much theorizing, but here are just some little things that felt easter-eggy / tid-bits of information meant to entertain the especially dedicated reader lmao.
Earth and Fire: Cassandra 2 is present at the Athens fire
"This is Cassandra 2. Can’t find Earth 8. Nothing but smoke and burning trees here.”
Rono later acknowledges that Cassandra 2 was doing ground firefighting at Athens in Earth Prime
Earth and Air: Valeska mentions Jerez
"Valeska seemed to stop to think for a moment. 'Actually, you’re right about that. The last time I saw Peregrine, he was besotted with Jerez of Cassandra 2.' Gradin raised his eyebrows. 'I don’t think Peregrine stands much chance there.'”
I think it's funny that Keren is starstruck when he meets Valeska in Earth Prime but she and Gradin apparently know of Jerez in 2788??
Earth Prime: the six raw fish
"'In which case, you’ll know the contents of the stasis box I excavated during my wedding.' I laughed. 'Six raw fish.'"
I feel like it's meant to be implied that these six raw fish were put in stasis during the Scavenger Exodus era.
Zeta Sector 2788: I can swim like a fish
Drago, on a beach: "It was too dark to read the neat inscription about how a boy of 17 had tragically drowned on this beach, but my hand could trace the outline of the larger letters below that had been carved roughly by hand with a laser pen, and I knew exactly what they said. 'Of course I didn’t drown, you idiots. I can swim like a fish!'"
This one confuses me a little– I took note of it because it uses the exact same phrasing Torrek uses to describe Bard, aka "can swim like a fish." Idk what the intention was with pointing out the inscription on the statue, but my thinking is a) Drago is at the beach of Lake Galad b) some kid did die there, probably a long time ago c) Bard, being funny, added the inscription at some point
Am I missing something obvious??
Anyway that's all I can think of for now, other than the Drago ice cream incident, which has enough scattered mentions to warrant its own post I think
