Brandon is definitely a good guy. The three brothers could have paid a little more attention to his situation, and made it clear he could crash at the hotel after the party. At least they're getting a bit more aware of the crew's situation thanks to Brandon's. Is it really work ethics? Getting to become the front man for your favorite band is not like taking up any job, so you'd do anything for the position in the beginning.
I hope Helen tightens the bolts a bit on the whole business stuff, so the guys can focus on creative stuff, and let her fire Gabe, who doesn't end up being the hero as I first thought. Something came to my mind about a lot of Helen's reactions: in her job, and since she's rather bossy, she should just call a meeting to announce her decisions. I mean, it would be less fun for us readers, but professionally better if she handled the Brandon situation all on her own. I think fronting a few hundreds of dollars for clothing is no problem for her, and if Brandon is accommodated and fed, he may sure wait for a bit before he gets a paycheck.
As for the Scar, is he some kind of restaurant magazine reviewer?
