So wrong: facehuggers dont implant same host twice or more, and no they dont use other openings, earlier experiments it said and theory and not the facehugger we know where its clearly stated otherwise in movies, games, books etc they need the embryo implanted in the chest area by the mouth.
Jumping the shark by a mile Johnson.
I so hate those ugly freaks of nature mutated facehuggers, centerpied facehuggers mutations blegh.
