I refuse to abandon my theory that this is the same Rohan from the original continuity and he somehow either slipped through the timelines or prevented himself from being rebooted with Heaven's Door nonsense.

If that theory holds up then the lava rocks and/or diamond might also be connected to the old timeline, possibly the last remnants of it aside from Rohan himself.

I wonder if the group is gonna break up over the valuables, since Rohan doesn't think they're trustworthy.

Rohan doesn't really think anybody's trustworthy. He's always been a suspicious loner. Koichi is really the only person you could say he actually considered a friend or ally; everybody else in part 4, he just tolerated at best.
