I was thinking about the Plodex, and how it was that they had managed to become such a force to have been able to capture Alpha Flight. Where did they come from? The Master had only found one surviving pair of eggs when he was in control of the old Plodex ship, had there been others I'm sure mention would have been made.
So I see the following possibilities,
1. There were other eggs that survived from the same batch that Marrina had come from,
2. A new wave of eggs, or a new Plodex ship landed, and did it's thing.
3. (this is the one I like) The eggs that Marrina laid before she "died" have become a force to be reckoned with!
