Han resurrected by Eteon

Can't rule it out, if he didn't get out of the car on time and suffered burns and injuries, then the reason he's back is that Eteon, the coprtation introduced in "Hobbs & Shaw" had "rebuilt" him and infiltrate Dom and crew and go after Deckard Shaw. But Han working for Eteon wouldn't be revealed in 10 until Hobbs and Deckard return and I guess Eteon would wipe his memory and when Dom would ask Han how he survived, he'd reply he doesn't know how and woke up in a hospital bed which was staged by Eteon.
