Aaron admits to his brother Mark  that he stored fertiliser at the school, which was what
 caused the explosion once the fire started.
However,
 upon learning of Aaron's involvement in the fire, Tyler 
is stung to discover Mark wanted to stop Aaron from confessing to the 
police.
Although Mark explains that it was a temporary measure to 
protect Aaron until the real culprit was found, Tyler remains hurt due 
to the fact that the same treatment did not apply to him when he was in 
trouble earlier in the year.
As Tyler maintains that Mark trusts Aaron more than him, Mark insists that buying a house together proves this is not the case.
However,
 this lands Mark in the firing line with Aaron instead as he was unaware
 of the house purchase and wants to know why he wasn't involved.
Defensive
 from Tyler's attack, Mark reminds Aaron a house is a big investment and
 Aaron is terrible with money, causing a big family divide. Will the 
brothers be able to work through their differences?
