What if Ezra was out longer, and didn't get his helmet at that moment? What if the Pergils found a way to stop the enemies? (FROM the episode 'The Call' )

Ezra wants to leave the Ghost to explore Capital City again. Typical. Ezra goes to town by himself. No problem there. Ezra returns with an array of cuts and bruises. Yep, everything's per- WHAT? What happened to Ezra? What's going on? Who did this? What were they planning? What will the rebel Padawan have to face and will he be able to do it alone? Crappy summaries! Yay! XD
