"Dwalin and Balin." Dwalin introduced himself and his brother as they bowed politely to the skinchanger.
"And do you call two 'some'?" Beorn queried with a raised eyebrow. 
"Well, no..." Gandalf admitted as he tipped his head to the side and tapped two fingers against his forehead, as if taking time to think. This was the next signal, and Gloin and Oin ran out to join Dwalin and Balin. 
"Ah, yes!" said Gandalf merrily, as the two dwarves tried to smile and look friendly; "Here are some more of our happy troop!"

Beorn eyed the wizard skeptically. 
"And do you call seven a 'troop'?" he seemed almost mildly amused by Gandalf's blabbering.
