Tear Jerker / Maximum Ride

• At the end of Saving The World and Other Extreme Sports, Jeb Batchelder's son Ari dies before Jeb has a chance to say goodbye. Jeb goes into a full-on Heroic BSoD, repeating "I'm so sorry" over and over.
• Ari's funeral. Made even worse with how Fang has these words.
  Fang: Well, Ari, I'm sorry that it's ended like this. You were a decent little kid, and then you were a total nightmare. I didn't trust you–until the very end. I didn't know you much, didn't care to. Right now, that feels like the biggest tragedy of all.
