BTW word of god says the Red hood in G end is really truly Red hood, not anyone pretending to be her or anything. Red riding woods Red hood and BS 1 Red hood are 100% the same Red hood (she recognizes heinrich and he recognizes her, same move set as well) and most likely the same as bs 2 (moveset again, hotel scene, and travel assist from Node. Also Red hood is the only companion not present during any ending in bs 1, she gtfo before things went south even in her character ending and she will give up her fairy tale willingly, instead of fighting, under the right conditions and in D end she isn't present at all in the cutscene even if you summon her in battle).
