Pedro

To be fair, Verso's soul (the ghost kid) was the thing that kept the Canvas "alive" so it was more manifestations of his soul - and of Clea's to an extent (they kinda made the painting together) than anything else, I think. So he had every right to end it, rather than be the slave of a sister whom he sacrificed everything for. It is a bittersweet ending, not the "good", but the right one though.
