I’m happy with how Marvel brought Cyclops back to life in a believable way. Kid Cable finds a scientist, or engineer, named Paul Douek, whom Cyclops saved 10 years ago in their timeline. Kid Cable gives Paul a failed device created by the Avengers to contain the Phoenix Force, and asks him to create something similar but smaller in size.
Once the device was ready, they both went to Muir Island, where Cyclops’ dead body was located and surgically inserted it to his chest. Then during the events of Jean Grey’s resurrection from the Phoenix Force, the Phoenix temporarily brought Cyclops back to life in an attempt to convince Jean Grey to stay, or merge with it again. The device Paul created was able to siphon off power from the Phoenix Force, which charged itself in due time and resurrected Cyclops.
Not confusing at all!
So happy that Cyclops is back.
