While causing trouble recently around Bullworth, close to the school, I had opportunity to run down the sandy path to the water at the South-East side of the big bridge to escape the two Prefects chasing me, Edward and Max. Jump in the water and swim around there a bit while they throw bricks. After a while, the meter goes down, and they will start to leave.
But it doesn't stop there, not for me. I will bring Jimmy out of the water far enough to be able to shoot them. Three hits with the Spud Gun and they're down. Usually.
Max went down alright, as usual. But when Jimmy was shooting Edward, he kept getting back up....and up...and up. In total, I shot him 16 times before he would stay down. Extremely unusual, to say the least.
