Eh, I think this is set before the Terrigenesis outbreak.
1. Episode 2 states the bus crash happened 1 year ago in Jan 2014, which means this is about Jan 2015 or just a few months later. If it was real time then rounding down to 1 year instead of up to 2 years is just weird.
2. Terrigenesis outbreak happened May 2015 and didn't become noticable until later on. Shield is pretty close to real time so start of season 3 is roughly September or the last quarter of 2015 and it wasn't confirmed to the public at all until the first episode where the President addressed the problem and announced the ATCU to regulate/contain those affected.
3. When Luke and Jessica talk in episode 3, Luke doesn't seem to be aware of many other people with gifts/abilities apart from the Avengers, Jessica and himself. I'm sure both of them would know about the Inhumans, especially after the president announced it. The whole world would know and it's not a subject you'd forget, people turning into "aliens" with powers. And if this is set after that announcement, it just makes Luke seem dumb.
Other eggs I spotted
Of course "Jewel" costume and name.
Patsy Walker
Kid in a Cap costume.
Much more references to the Battle of New York. While Daredevil shyed away from it (kinda), so far it hasn't just been referred to the incident. We hear more about how the Avengers are seen as destructive and even killers, rubble and fire raining down from the sky and aliens were name dropped, something Daredevil didn't do.
SWEET CHRISTMAS
"I'm bulletproof" line from the comic, a bluff that's brilliantly called.
The viewpoints of superhumans and Civil War is again teased and built up.
Only starting episode 6 now
