The chuckling might have come from John, but Eddie made no move to show any amusement in the slightest. He found nothing about the situation hilarious, or even worth a chuckle. But he wouldn't take that moment from the other man. Humor was different for everyone.
He studied the vampire. They could have had similar experiences, but Eddie was sure that the other man wasn't alive nor did he bear any ability to sustain something like the symbiote. That had been proven. John wouldn't know what it was like having to satisfy the parasite, to know you were a host for a bug with no cure because you had no other choice. The scales were never tipped in Eddie Brock's favor, but he was working on that.
"There is an enemy here," Eddie explained, changing the subject to something easier to talk about. "A Spider, he wears red and blue." He hoped that if John saw the Spider, he could at least capture Parker and hold him captive until Eddie could get to him. And it wouldn't be bad to have another pair of eyes on the lookout. "If you see him, please refrain from hurting him too badly. I want to destroy him myself."
