This question has been bugging me for a while. Maybe it is a bit overthought.
Does Nick Fury really need to send a pager message to Captain Marvel after Thanos' snap? I mean, there is only a 50% chance that Captain Marvel would survive, and if she does, she will come to know what had happened. If she cares about Earthlings, she would naturally come here for help.
So, was all this pager thing unnecessary?
