I think Kane feuding with Cena is like "all our faces are occupied and we can't have Kane feud with Henry because we want him to be a heel this time. Oh hey Cena's free." I've seen better Tombooking than that...! Either that or it's just going to be like, Kane ignores Cena from now on and just wanted the wristband, which be amusing character development for Kane if nothing else.
Like Biscuit's approach could work but I don't think it'll go that way
