You explained it well! :)

I think lol.

Let me reframe and see if it adds up the same on your end. Aeons are hosts to Spirits. Spirits are controlled by their hosts. Spirits execute moves/attacks/techniques through the host's body via their permission. Therefore, the blood manipulation is being done by the Spirit, not the Aeon. The Aeon is simply directing the Spirit's actions?
