2 theories here
- There was 1 egg on board, with the Facehugger able to implant 2 embryos
This makes the most sense, a facehugger for Ripley and one for the Ox.
My issue with this, is why did the Ox's Alien come out long before Ripleys. Does a Queen embryo (which we know because of Resurrection) take longer?
- There were 2 eggs on board, one for the hugger for Ripley and one for the Ox.
Either way, we can debate how the egg(s) got on board in the first place (and that's the biggest issue) until the cows came home. Was it Bishop or did the Queen stow one away, if so, when?
I could both things, I could believe they were 2 eggs but we only saw one or that there was a 'Queen hugger' if you will. My issue is how it got there in the first place and why there was such a delay between the Ox and Ripleys chest burst. The Runner had time to pretty much wipe out the population of Fury 161
