Broke my Fibula, how long till i can walk by myself?

I'm 17 and 2 weeks ago I broke my Fibula only about 1 in from the ankle, and 3 days after the break i had surgery to keep it stable, i have a plate and 8 screws in it. I have no pain or swelling at this point, and it doesn't even hurt when i put my weight on it, just a minor annoyance. I went to the doc today and he said it was looking great and he could hardly see the break anymore. I got my staples removed and a new cast. Now I know for sure I will have this cast another 4 weeks, but I never got a clear answer on whether or not i will need a walking boot after. In your opinion, if he said it is healing great and looks fantastic and can hardly see a break, and he also said the reason i do need this cast is just to make sure the plate doesn't warp, will i need to be in any more casts or boots after this or will I have a virgin leg again? I know I will need to ask my ortho for sure but what is your opinion?
