I don't know how this should work. I'm at a point where one protagonist has just met another protagonist in prison. I plan on making them have a very strong bond built up over time and I want at least a little of that bond developed over the time they're in prison together. One of the protagonists is being forced by the warden to fight in an arena against opponents significantly more skilled than he is, but will eventually be able to hold his own against most of them, and even out-match a few. I want two things to happen over the course of three months, when the protagonists make their escape, without writing every event and dialogue of every single day. 1: The protagonists to develop a strong enough bond that one will help the other escape and stay together til the end of the story. 2: One of the protagonists to learn hand to hand combat to a proficient level. I have no idea how to write a time skip here without it sounding cheesy or forced. Also later in the story I was planning on the protagonist that fought in the arena to be formally taught some form of martial art or self defense to the point where he can win a 5 on 1 bar fight. I was thinking Krav Maga, but now I'm not so sure as it seems to be a 1 on 1 fighting style. Can anyone recommend a more fitting martial art for my protagonist to learn?
