Click the flag Silverpatch's kits were murdered, and she vowed revenge on Moonblaze. Firespark finds Moonblaze, and kills him, but then slips, and falls into the river. Silverpatch isn't able to save him, and thinks he dies, but actually he washes up down the river, and when he regains consciousness he returns to Silverpatch :)
