They are usually paired in groupings of two to guard the entrance to a site, and speak in unison.

They could be seen in charge of entry for the Battle of Speed waiting for Graham to bring his steed.

They are again seen involved in the argument between the Troll Guild and the Royal Guard over how to protect the back of the trolls from the guard's feet. Graham gave him a sock to fix the problem.

Finally they can be see at the entrance to the Tournament Theater while they prepare it for the Duel of Wits.

Behind the scenes
The Royal Knight is listed in the character lines in the script (without the designations of being RG1, RG2, or Larry or Kyle) thus indicating they must be either an unspecified Knight or other unknown knights in the Royal Guard.
