Does anyone know if Sydney's parents were ever divorced? The marriage was valid and I have not found a confirmation either way in any of the episodes. Especially, in season 5 when Irina asks Jeffrey, "Where is my husband?"
lol well the marriage wasn't valid because she was married under a fake name, with fake documentation and a fake identity. So Irina Derevko was never married, Laura Bristow was but Laura Bristow is also recorded to be dead after an accident. So Jack and Irina aren't legally married o anything.
