So I just finished Runaways and apparently they basically show that the past is able to alter the future of the same timeline, which basically means that people can be erased from existence. However, Steve Rogers, Deke Shaw, and Nebula killing her 2014 self are proof that it's not really the case. So I'm really confused how the future Runaways are disappearing from existence. Unless TVA? Sounds a bit far fetched though.
