So I am completely confused, what happened to Ezra in 'Homecoming Hangover'?

I agree. When he got that voicemail on his answering machine, I didn't even get what was going on.

I was confused too and then I listened to the message again. I think Ezra went away for a job interview because he couldnt stand to be around Aria any more. The message said we cant wait to meet you and something about the job being great for him. :( I really like ezra and aria together. They are great together!
