#63: MCU: Soul Stone
I don’t know about you guys, but I hate the Soul Stone most out of all of the Infinity Stones (which is not something that I ever expected to have an opinion about). It just seems to keep leading to the deaths of characters that I care about in the Marvel Cinematic Universe.
This fan theorizes that Thanos adopted Nebula specifically to sacrifice her for the Soul Stone, understanding its terrible price, so that Gamora wouldn’t have to die. Of course, the problem with this theory is that it supposes that Gamora loved Nebula, which is up for debate.
