He stands alone because no one will come near. 
He stands alone, unloved, unfriended and silent.
He stands alone, looking and searching for anyone who may want to talk to him.
He stands alone, patiently waiting for the opporunity to arise for a game to start.

Before anyone can come to his aid, he is replaced. 
Just like he knew he would be when the time reared its ugly head and told him he had failed.
He will have to do it all again.
Over and over again.
