The same type of situation could apply to Tea. Ross could have been crazy obsessive with Tea. Maybe he thought he was doing her a favor and told her he was the father. Perhaps, he pulled a Todd and sent Tea's child away and told her the child was dead. Maybe, Tea's dark secret is that she had Todd's child, she thinks the child died shortly after childbirth because she didn't have access to proper prenatal care due to being on the island and she knows Todd would blame himself for that.
The only thing that is strange is that she tells Blair, "Maybe you can do something with this." That doesn't seem to apply to a child. That seems to apply to a secret about Todd (are we 100% certain his mother is dead?) or a secret about Tea and Blair, like them being sisters.
