[At the sound of the door opening to his bathroom, immediately there's an Eridan stomping his way towards it to yell at whoever it is thinking they're about to enter -- As if he would let anyone in! However, once he realizes it's his moirail, he pauses mid-opening-his-mouth-to-yell and shuts his mouth.]
-- Cai!
[That is, until he calls out his moirai's name and scampers over in a much different way from his stomps before.]
Come in, come in. Just close the fuckin' door behind you.
