Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

Q: In Fantastic Beasts and Where to Find Them, Newt restrains Graves' movements with one of his friendly beasts and then proceeds to use the Revelio spell to... (spoiler)     reveal Graves' true identity, who is actually Gellert Grindelwald.   My question is, what gave him away? How did Newt realize that man was not really Graves? I was thinking maybe the speech he gave matched...    Grindelwald's ideas   ...and also the power and skill he displayed whilst fighting the aurors. Does anyone have a better explanation for this? Also, as a curiosity, what did...    Grindelwald   ...do with the real Graves? Maybe something similar to what was done to Alastor Moody in The Goblet of Fire?

A: How did Newt Scamander realize "someone's" real identity?

Q: In the iconic Battle of Stirling Bridge scene in the film Braveheart, English heavy cavalry knights charge with a lance in their right hand and a shield in their left hand.   I recently watch this battle scene again and noticed one particular thing: English knights should have carried close quarter melee weapons.   I understand for heavy cavalry, they are supposed to charge towards their enemy over and over again on their horses, but should they not consider taking a melee weapon with them, for example, a mace, a sword or a dagger so that they can defend themselves when they become dismounted.   I think it is a detail Mel Gibson overlooked when making this movie.

A: Are the cavalry knights missing close melee weapons in Braveheart?

Q: In the Flash tv show from DC in one scene of "Season 7 Episode 7 (@09:25)", Barry Allen gets struck by lightning and suffers from cardiac arrest. He came back to life by getting chest compressions by his daughter Nora Allen.  So my question is..   How a speedster gets affected by lightning?  I mean speedsters are created by lightning bolt according to stories about Flash. And they contain such amount of lightning energy called  speed force in their system. Shouldn't lightning should recharge their  speed force?   Any promising details would be appreciated on my confusion.

A:
Why does lightning hit affects speedsters?
