Cora or Suvi.

Where does it say/implied that Vetra is related to Saren?

We don’t know for sure if Cora is Jack Harper’s daughter.

Yeah both share a last name and the name Cora is similar to and can be derivative of Coré.

I think it’s implied as a knowitallinsidejoke, otherwise just rude assumptions.

I am sad people cannot make up their minds though. If no one in the game strikes your fancy enough to start a romance, consider this - you don’t Have to have one.
