People might've noticed Bad Ben who looks worse for wear as his scarring has spread a bit due to his 'medical emergency' around as he's been hanging around Good Derleth for 'medical observation' since mission 'tag Baymax'. He might have also 'lied' about how the presence of that many Monoliths are aggravating his degeneration. He's been the perfect guest though and typical cheery neighborhood 'Spider-Man' attitude. And just eating all your food. It's been awhile, ok. (I've been meaning to toss a post up from good Ben about this, oops)
Good Ben would've been making the rounds and putting on the usual smiles, but anyone who knows him/is observant would notice he looks a bit more tired and reserved than usual.
