This is interesting to me that everyone thinks she will betray Alpha in rebellion of the Whisperer ideology. I felt more like she considers "the Alpha" as its own entity rather than just Alpha the person. I was thinking more along the lines that Gamma would eventually rebel against Alpha for not being alpha enough, especially if she finds out about Lydia being spared while she killed her own sister. Alphas lack of dedication to her own ideology will be seen as weakness, as we saw before when Alpha went to retrieve Lydia, and will be used to challenge Alpha as the alpha. Beta would obviously be a stumbling block, unless of course she can convince him too that she is more alpha than Alpha.

I know my theories are usually way, way off, lol, but having not read the comic it's fun to play around with them.

 

I agree, I think Gamma will betray in Alpha, for the reason that Alpha is not alpha enough to lead the Whisperers, and that Gamma is more dedicated and loyal to the cause, with no weaknesses (ie. Family member) to hold her back.
