alright so i know some of y'all are like "oml another frackin theory" well sorry not sorry tbh XD anywhoozles, my theory
well its actually my mom and i's theory but this is it.
Qrow is Ruby's biological dad. Now i know your mind is blown and youre prolly thinking "no frackin way this chick is on crack or something" but just hear me out...
Tai and Raven were originally together right? right they had Yang. Now the way Qrow talks about Summer leads my mom and i to believe they were a thing Summer got pregnant wanted to get serious with Qrow but obviously bc Qrow is selfless he decided to break it off bc he had missions to do and he didnt want his semblence to hurt the person he cared for or their unborn child, so they break up, but around the same time Raven leaves Tai so Summer and Tai start spending more time together (banging an stuff XD) she wants her baby to have a father so she decides to "make" the baby Tais....
now i know there is no solid proof and its mostly speculation but it could be a hugh probability. Now some people are gonna be like "OH HEELL NAH NO WAY!" and i completely respect that like i said just a theory but Qrow obviously has a closer relationship with Ruby which you can see countless times bc he knows Ruby is his.
Like i said theory, speculation, hoping its true but we dont know for sure so tell me what yall think if im actually crazy and pulling stuff out of my arse or if there could be some "truth" or something to my mom and i's theory...
