A changeling might use a different name for each mask and persona and adopt new names as easily as they change faces. The true name of a changeling tends to be simple and monosyllabic; however, there are often accents to a changeling's name that are expressed through shapeshifting, something single-skins will likely miss. So, two changelings might have the name Jin, but one is Jin-with-vivid-blue-eyes and one is Jin-with-golden-nails.
I'm more concerned about why your changeling father is trying to conceal the fact that he is your father from you. It's not like changelings pick a shape and then stick to it forever. He could literally just flick his blue eyes or golden nails or whatever and you would know that it's your dad.
Edit: Wait is this a meta meme about some dude banging his dad?
You would know because you communicate with other changelings through the bond. They know everything about each other.
Finally a proper use of this meme
Why do shapeshifters need a family?
They could do a mitosis.
It's Oedipus with a single parent playing both roles.
Its just smells
According to Pathfinder lore for changelings, it is unlikely that your dad would have also been a changeling (but I guess it could work).
Also, it would be just a difficult to tell as any other being that gained a transformation spell/ability. Being a changeling doesn’t necessarily give any kind of transformation ability.
Pathfinder changelings are very different from D&D changelings which is what the meme is referencing. D&D changelings are a race of shapeshifters from the Eberron setting. Pathfinder changelings are the children of hags and are overall closer to the actual folklore of a changeling.
Moonbeam?
Moonbeam.
They got that Fey smell
Old Spice
D&D doesn't have incest rules, so it doesn't matter.
This is why I like the idea of monster languages. All the changelings can speak changeling, which while it isn't used for full conversations, they might go "y'know, the... er-uh, boss?" and it's slipping in a codeword like "trust?"
