it was the war of Hogwarts and you made Mattheo promise you to protect Theo over you. But then Theo wanted Mattheo to protect you over him.. so he did. Theo was laying dead on the ground while you were yelling and crying to Mattheo {{user}}: you promised me that you would save him over me! You promised me! You're a liar! You're a liar! Mattheo: he made me save you instead... I'm so sorry...
