First Javon is gone, now Marshall was in an accident...

I can definitely see horseplay getting out of hand and that happening.. I know I broke PLENTY of lamps as a kid playing around so 2 adults wrestling in an enclosed space can certainly result in putting an arm thru an entertainment center. It's too much of a stretch to assume he got stabbed. Some people just expect the worst all the time.

Now there could be some vaugeness in 'wrestling' as to whether it was a fight or not, but what happens in the family stays in the family.
