That's exactly right. What I found interesting was that Surfer (in the not-too-distant-past-memory) seemed to be very sympathetic to the symbiotes - saying he was no threat to them. It continues the idea that although the symbiotes protect Knull, and Knull created them, that they are NOT evil or bad, but merely his innocent, living creations that he seems to show no love for, but on the other hand, they do anything to protect him. I think Venom has shown this past year that such devotion can CHANGE if a symbiote ends up bonding with other entities - but Cates has managed to make me feel bad for symbiotes! They are born innocent despite Knull's clear evil.
Am I the only one that really, really, really now wants to know who that "other" God of apparent light in the old Thor story that fought Knull to a standstill is? It's like one of the biggest mysteries now after seeing Knull's weaknesses in this issue.
