Liz... they're taking our home from us. They want to kill us... and they might. But when I look in your eyes, I... I don't feel angry, or deprived. I feel like the luckiest half-human on the planet. You're pure... you're true... and you're real. And right now that seems like the only thing that's important. I want to be with you Liz... forever.
Then we'll take those twelve days... [He places a diamond in Liz's palm and closes her hand around it] And we'll live twelve lifetimes. Liz Parker... will you marry me?
(struggles to form words, then speaks) ...I wanted to say that this thing has been screwed up from the beginning. You and me. Us. Just the whole long, stupid story...
But I wouldn't trade it for anything. It's meant so much to me, y'know. From day one, from the moment I kidnapped you and stole your car... I knew you were the girl for me. I never wanted anyone else...
I'm a member of that group of... outsiders. I always knew I was different and for a long, long time, all I wanted was to be another face in the crowd... but in the end, it wasn't possible. I guess it never was. So from now on, I'll just concentrate on being who I really am. Some of you might not like that. Some of you might even... find that frightening. But that's not my problem any more. I have to be who I really am and let fate take care of the rest. So... thank you, Roswell... Thank you for... for letting me live among you. Thank you for giving me a family. Thank you for giving me a home.
