That's the way I feel about it too. I mean, they're ten, and while I don't doubt that love is possible at that stage, given the characters we're talking about I'd say it's more of a deep-rooted friendship between the two. Regardless, it still makes an awesome scene.Though opinions on this subject may diverge, I like to interpret that as a true "friendship" kind of love that Millie and Ozy share. I've always seen them this way, and it just feels right to me. But that's just my own view about the situation.
This isn't the first time something like this has been drawn (In Memoriam, Lakeside Line Art, January Keenspot newsbox), but the whole "dream" context of this one makes it undeniably sweet.
On a side note, I'm loving the signed print of In Memoriam I ordered.
