Time for Visitor To Leave?

Children have an invited summer house guest. The older child never wanted this summer visitor.  The older child wanted another friend there. The visitor arrived, and the older child immediately set forth an agenda to send the visitor back to his own home.  With continued created chaos being initiated by the older child, in a matter of days, the parents began to see a problem that was not getting better.  The older child had the parents fighting and the younger child was more irritable as a result. Finally, the parents reluctantly sent  Barry home.  It had nothing to do with Little Barry, but all to do with what the older brother was willing to do to get Barry out of his home.
