First sentence 

Hi there! Thanks for the edit, I really appreciate you helping to improve the article.
I have something to say about your edit, however, and I wanted to take you aside a moment and work this out.

The problem sort of exists with the original too, and i've been trying to think what we can do about it.
See, a sizable chunk of people still do know it as 'the alien from alien', and our job is to correct those people when they look it up.

Its a problem with the article I was planning to tackle after the xenomorph issue was settled (if it went that way). The way you have phrased it sounds like its just some uncommon secondary name, which is not ideal, but neither was the way I did it.

Basically it needs to say "You might know this as alien, but you would be wrong", but in wiki language. I've hit a brick wall with how to do that. I'm hoping you might have some ideas for that.

Do you think we could work out some nice sounding way to introduce the article a bit better than it currently does?
