Curate, connect, and discover
I have this fun little headcanon that, since the main five elements are connected, when one of them dies the others can feel it and it’s actually physically painful. Like, really physically painful. It’s never happened before because technically none of them have actually died before for real, but once it does happen they’ll instantly instinctively know exactly what it means.
Additionally, maybe until the element finds a new host, Lloyd loses his powers because they come from Jay, Zane, Kai, and Cole, and if, for example, Jay dies, the lightning piece in his energy powers won’t work anymore.
But yeah imagine everything is totally fine and one of them is on a solo mission that was supposed to be pretty straightforward, and everyone else is back on the Bounty and then all of the sudden they all feel this searing pain like a piece of them is being torn away and they realize that something has gone very, very wrong.
