If Tink had a hand in Regina’s adoption of Henry, that could connect her in a way to multiple characters.
Question here though, what did they say exactly and how much is the reporter interpreting? No direct quote given, but at CC they did not say on the ship but panel. Did they confirm “she has met Hook, but it is not her only connection” and then the reporter just extrapolated that the other connection is on the ship?

“If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?” -- Lewis Carroll, Alice's Adventures in Wonderland & Through the Looking-Glass
