<p>First and foremost, i also fought it was more like Rose consider Greg as a pet, at least a little kid. But, with the episode "Lion 3", we must admit that they fell in love, at least Greg. Rose, since the start, seems to have some attraction for human. So... after all, we can contend that it was just some curiosity at the start ( a guy who want to go in space, and very fair ( he gave her a free T-Shirt ), then, this feeling transformed into some affection. However, it's not sure she loved him, may be she just wanted to create Steven for an experience or to see what being a human looks like.
</p><p>Concerning Greg is perfectly the stereotype of a young boy who really believe in feelings, so i find it difficult to say that he wasn't in love. He wouldn't play with that.
