Everything was fun and disturbing, especially the maggot thing. Also, I was thinking, "y'know, if they did do a crossover 'tween UU and 616, I'd hope it was really innocuous and subtle, just like the two Reeds can talk to each other. Just a nice little touch, not a huge mega-event." But of course, it was not the 616 universe, but the Gotcha Universe.
Also, in Ultimate E's face. All this time he's been going, "they're gonna meet the 616 F4! It's going to rock" while all along, it was obvious such a thing was never going to happen. Despite the obviousness, he couldn't handle it, and even know continues the dream that this is 616 but just in bad shape. Poor E. I just hope hE doesn't joke on all that humble pie with steamed crow he's eating because he was so unbelievably wrong.
Just like Ice and the Ultimate Mad Thinker ordeal.
