Gurgi looked scared

Look at Gurgi! 

He was scared that one of the Horned King's deathless Warriors 

hit the Door with a War Club with Spikes on it 

and then Gurgi ran down the Stairs and 

he was quickly panting before he could untie 

Taran, Eilonwy and Fflewddur Flad. 

That was a frightening Part of "The black Cauldron".
