Lambert getting impregnated by the Alien's tail could be possible, if the tail was able to enject semen into the victim's body. Maybe the tail functions as being able to paralyze and impregnate or the tail stung Lambert and then the Alien "regurgitated" in her mouth. I always thought that tail of being a stinger of sorts and having some kind of paralyzine poison at the tip. Yes, I know the tail also impales enemies, but that's just another ability of the tail, obviously, for self-defense.
What if the egg-morphing method begins with the tail? The face-hugger oral rapes its victims when they are alive, maybe the full-grown Alien has its own way to "rape" its victims by injecting something through its tail or paralyzing its victims with its tail and then is able to "regurgitate" into their mouths.
Who's not to say that after killing Parker, it also began the egg-morphing process with him? There were two people the Alien killed in the same area, so maybe, instead of taking the time to haul them back to the "hive", it quickly killed them and began the egg-morphing process right there, possibly through the stinging of the tail or maybe it "regurgitated" in their mouths.
Why was Lambert's body hanging?
As we saw in Alien, it killed Brett and then began the egg-morphing prcoess, so maybe the Alien kills to get its fill of food and then begins the egg-morphing process. So, this egg-morphing process would have to do with either paralyzing or killing its victims, first.
In AVP-R, with the shot of the woman in the hospital bed and the PredAlien near her, we can certainly tell that the PredAlien is probably going to do the "regurgitation". We don't know what is wrong with that woman in the hospital bed, so she probably can't move for some reason.
We can bitch and complain about this new regurgitation method, but I'm really curious of how it will look on-screen.
