Obi Wan vs Anakin
Anakin is emotionally hindered similar to how he was in LoE and RotS. He hasn't eaten or slept for let's say about a week.
Obi Wan is morales on but determined to win.
Fight takes place on Mustafar.
Who wins?
I think we all know what with the common consensus being that Anakin could pose a threat to Sidious and Yoda. 🙂
