alien got surprise elemnet, kane did not see the hugher before it jumped straight to teh head, kane probably became stunned
ripley knew where teh hugher was and waht it was goign to do
aliens hughers were weaker for staying longer out of egg and probably most of tey cells were polarized silicone so werent normal?
off topic:
why didnt aliens hugher melt trough the glass containing them?
how come kane's helmet has no hugher fingers marks? they must be really flexible!
