Hydrian is there like a shadow until you needed her, then suddenly she would be unavailable. Her ready smile is only for those who give their things freely and don't require any help in return. Once their personal crisis would be over Hydrian would re-emerge from the crowds and re-insert herself into the group, cracking the jokes everyone loved and paying them for their company in her favorite “currency”- gossip. Hydrian knew the dirt on everyone, and if you aren't someone dear to her, she'd be free with that information to give to whoever she wanted - at a price. With her or against her, it's how it is.
