I'm not sure if this has been asked here. I have found some forums elsewhere on this topic, but maybe the minds here have other thoughts.
In X-Men: Apocalypse, Havok, seeing Apocalypse and his horse-people abduct Professor X, tries to blast them away, only to blow a power-source or something with enough destructive power to blow up the mansion.
At the time, Quicksilver arrives at the mansion. He then suddenly "feels" the explosion or something and proceeds to save everyone, in a very cool scene to some awesome 80's music.
Thing is, how? How did he know the place was set to blow? Could he feel the vibrations in the ground? And if he has some gift of foresight, how did he not know that Stryker, who appeared shortly after, would stun everyone? And going with vibrations, seeing that Havok was not that far away from the blast to begin with, why couldn't he be saved? He was at least 5-10 meters away from Beast, who was saved, when he shot the blast.
This movie, unfortunately, left many holes in the plot. This might not be a big one, but it's a rather curious one, at least for me.
