Fazed was just saying, there are 3 main paths, with variations of the three.
Beta - more beta points than alpha
Neutral - this is usually counted as more alpha than beta
and <40 alpha points though some choices can allow up to 59
Alpha - this is usually >=60, though some choices may happen at 40
There are also the two flashback paths: sexual or violence. This path is decided in whether you push Lucy in chapter 1.
The other main variation is whether you told Lucy you loved her in chapter 3. Loving Lucy gives nicer interactions with her and changes the chapter 3 shower scene. It also restricts some options. For example, in the chapter 4 shower scene, there are 5 options for finishing. If you love Lucy, only 1 option is available to you, because you love her.
There is also a chapter 4 choice which will give you the alpha or beta flag, or you can choose the neutral option which doesn't give either. Those flags will change some options, from now on. This is your decision on how you want to finally handle everything, regardless of the deal you made with Big John.
