Well.....

The only thought I had was maybe it's left open for a possible sequel

Well he had to tell Chanel an answer right away. His answer to Chanel was not really a definite no. It was what he thought. If she said she wanted to do it then he can call always them back and say she can do it, which is likely because they liked her. It was also why he was calling as her agent.

By the end I was sick of the character, because I thought she had that look throughout 90% of the movie - a sullen, uncertain "uh, I dunno" kind of look. Very much a teenager who doesn't know anything about anything yet. I understand how that lifestyle for young women has a lot of pitfalls and I could never have done it at 18, but she just seemed so vacant and lifeless that I'd get really impatient with someone like that in my life. Only in modeling would it be valuable to look bored and/or b!tchy all the time.
