(Most of my thoughts on the matter have been written down by someone below. So I'm not going to repeat it.)

If you say it like that then there is one thing that you need to explain to me first: Why the hell were Luffy and Co. ready to take on the freaking World Government to save Nico Robin even thought they knew her for only a couple of weeks? She isn't even needed, like all previous members. Not to mention that she was their enemy before - and not a minor one.

I agree with Levi's time calculation. It's been at least a few weeks Franky and Brook have been sailing with Luffy. And even though that's not all too long either, just how long do you take to consider someone a friend? (Franky and especially Brook seem to be the kind of people who make friends very, very quickly.)

Before you say that there is a difference between a friend and a friend you would risk your life for, this is manga logic. Everything has to be a little more extreme than in reality. Otherwise it'd be damn boring.
