So we just learned that there is a hierarchy when it comes to who has control over the Seraphims. It goes The Gorosei, then Vegapunk, then Sentomaru, and then anyone with a command chip.
The interesting thing here, is that we also have found out that commands can not be issued over Den Den Mushis. With Vegapunk pretty much becoming an ally with the Straw Hats, the only way for the Seraphims at this point to be able to be a factor for the World Government in the EoS war, is if the Gorosei are there and are directly giving orders. This all but confirms the Gorosei will play an antagonistic combative role, at some point in story.
