Dan’s face in this is brilliant acting. The trio have all been awake for over 24 hours by this point, and everything seems to be in YKW and the Death Eater’s favour, Hogwarts is falling and people are being killed everywhere and just look at how Dan projects it all on Harry’s face.
Harry’s seen the dead bodies of people he loves and he just has so many emotions overflowing. He knows that Ginny, Ron, or Hermione could be dying as he’s talking to Helena, he’s so tired and over whelmed and he wants it all to end but he knows that he has to keep going despite how terribly awful he feels - not because of the prophecy, but because it’s the right thing to do. Because he needs to make sure everyone is okay and to save as many lives as he can. He carries such a burden for a boy of seventeen and yet he never gave up with depression or fear or exhaustion.
That’s why I love Harry as a character and a person, because even after all the thing’s he’s been through, his abusive childhood, seeing his big-brother-equivilent and his mentor die, being tortured, and always in so much danger, his heart is still so full of love. Yes he’s sometimes whiny and doesn’t always think before he acts, but he has so much love for everyone which is amazing considering what he’s been through - and that’s why he always keeps going. Not for himself, but for everyone else. He is torturing and exhausting himself and going as far as he can to protect everyone. That’s what I call a hero.
