I think you already have a hard proof that Odyssey Tiger Fold is dominant to Scotty Fold but in case you need a second proof.
Mom Birgit shows Tiger Fold
Dad Mikhail shows Odyssey Tiger Fold
Baby shows Scotty Fold
Therefore Scotty Fold is dad Mikhail's hid. Mom with Tiger Fold cannot hide Scott Fold. Odyssey Tiger Fold is dominant to Scotty Fold.
