Torpedoes can cause a detonation , which I think is what happened here . Might have been accidental , might have been deliberate . It would be very weird for a 127 mm shell from a Kagero to manage to get into a magazine , though that ' s also possible . If the Kagero was already pink , then any damage would be reflected back onto her . With detonating a BB , this is more than enough to remove the complete health of a DD , easily . Normally , you don ' t turn pink during a battle , at least I didn ' t when I accidentally killed a friendly BB once , only at the end of the match . That ' s why I assume that the Kagero might have already started pink . Then again , maybe if you get pink on a regular basis , the game changes and turns you pink immediately . In this game , 2 torps might have hit the Tirpitz , first doing damage and turning the Kagero pink , the second detonating the Tirpitz and reflecting the damage onto the Kagero . But these are just guesses .
