here's the idea LuaKitsune

Ezra is captured on the mission by the Empire. The Grand Inquisitor tortures Ezra to give information and join the dark side but Ezra refuses. So when Ezra doesn't break, the Inquisitor tries his new way of torture. Phobia serums. Phobia serums makes your phobia come to life when you are in an unconscious state. (You can use any phobia) the Inquisitor finds out Ezra's greatest fear(s) and uses it on him. Then the inquisitor leaves Ezra to suffer until his family arrives. Kanan and the crew finally comes and rescues Ezra a bit to easily until they find out that Ezra was mentally broken. Kanan and the others try to help Ezra through his broken mind of state.
