Forget about Adult Scott. He died.
Despite the fact that Namor has a weird-shaped head, balding hairline, plucked eyebrows and looks like an eternally angry Elf king think about it, both jean and namor have an aggressive nature. Between them, everything can turn out into something.
I see them as a couple who have bombing sexual chemistry with elements of domestic violence. But I'm not worried about Jean because she's freaking Omega mutant so she can easily put namor back in his place.
Also Nightcrawler and jean potential ship. She's not picky and does not judge people for their appearance.
Remember Wolverine and his bad hygiene?
Would you like to see Namor and Jean together?
