Unless you have an article on Alien's mortality and morality (or lack there of), I would advise cutting the chat if you please. Not even he can stop the onslaught of squirrels.
Incidentally, I've always thought of Alien as more of an enigma. Not really interested in anything other than self amusement and the pursuit of a laugh and possibly money. Whether or not he is immortal or immoral is irrelevant to him, I would have thought. But hey, what do I know, all I did was invent the beggar.
