In The Serpent's Gift it's mentioned that Melussina fled from Sezuan and (mostly) his family, while being pregnant with Dina. Where were Davin when all this happend? Also, where were Davin while Melussina was with Sezuan? He must've been 4 yeras old or so. Was Melussina looking after him and being with Sezuan at the same time?
