Wow there's a bit to unpack here.
That red squid has the line coming out of them in similar style to Cold-Blooded, except that's obviously not cold blooded. It does, at the least, confirm that some sort of echo or point sensor marking ability is back.
Ink resist lives on, but in sub form, meaning it's scalable. It could mean movemwnt speed in enemy ink, damage over time in enemy ink, or still both...but I doubt it's both.
Sub defense is interesting but I worry abilities may be getting a bit too specific if we're going to have a bunch of stuff like this. And then there's double quick respawn...which continues to loom over my impression of the game like a dark cloud until they actually explain what it means.
More:
Team-related QR seems more beneficial in like salmon run but if that's how it is now then so be it.
Remember, though, that respawning doesn't work that way in Salmon Run since you get the lifesavers instead (and you're stuck using Grizzco gear). Double QR is strictly a competitive thing...whatever it means.
