Damon watches the mushroom people enter, and, being no stranger to the supernatural (He's been to Hell for Hell's sake!) did not even bat and eyelash to the fact they entered through the portal, or the fact that they were giant.
Carl, on the other hand was . . . surprised to say the least. As he came back with muffins in a basket, he asks Damon what the hell he thinks those . . . things, were.
"Ah, Carl, that is the beauty of the supernatural. It creates things the human, or Scaercoin, find odd, but of which have existed longer than humankind, here or anywhere else."
"Still, sir, it is unnatural to be anywhere close to those things." When Carl starts being formal, you know it's a time when he's patience is tested.
Damon puts a hand on his shoulder to calm him, "Come, my friend, you've seen odder things adventuring with me. Now, let's go meet them."
Carl utters a curse under his breath, to low for even Damon, with his EXO enhanced hearing, to catch. But, as Carl says this, he still goes along with Damon, not to protect Damon, but for Damon to protect him . . .
