Mari and Sunny still have that argument in front of the stairs but Sunny gets away and runs for the hang-out spot before Basil arrives. When Basil does arrive no one is there. At the hang-out spot, Sunny gets pushed into the lake by Mari and she fails to save him. Hero was near the hang-out spot (Walking Hector) when Sunny got pushed and heard Mari scream. When he got there Mari was pulling Sunny out of the water. Hero then told Mari ‘Sunny has no pulse’.
The two end up walking back to the house Sunny in hand and place him in the bathtub, they both swear not to tell anyone the truth.
His death was ruled an accident or a suicide.
This takes a toll on Kel’s mental health and he becomes irritable and rude his grades also start to drop so he gets kicked off the team. Basil visits Sunny's grave often sometimes bringing Kel or Aubrey, he acts like the group therapist. Hero still goes to college and while at college no one told him Mari was moving. Aubrey tucks away her feelings and judges Kel for his outbursts over Sunny.
