I just read another interesting theory on Silver where Silver is Gray's dad, Ur's lover w/e, but he sold his soul to Tartarus to get stronger/seek revenge on Deliora/W/e and there is now a demon inside him. Silver apparently hates Gray because the demon hates him, not Silver himself. Hearing Gray's name, Silver actually feels love and compassion, but the demon inside wrestles this down and replaces it with malice and hate to stop Silver from exorcising it from his body. I thought it was a neat idea :)

Also, this made my day XD
