I fannaly figured it out! I know what branch the starlings are! I knew they weren't Tomas because that would be 8 Tomas in the competion.
They couldn't be Lucian because that would be 3 Lucian teams. That leaves only Ekaterina atau Janus.
Here's what I used to help make my conclusion.

1. Sinead jalak, burung perling runs a movie reveiw website.
2. The Starlings once built a bot to sail across the Carribean to explore a hidden island.

They wouldn't need to explore it if it was their base! the conclusion is that they MUST be Janus.
