Loki promptly gave 'some guy' - who had chimed in with his unnecessary opinion - one Helheim of a withering glare. It could probably be mistaken for a jealous boyfriend, even though that couldn't be further from the truth. It was annoyance. Simple as that.
"Yes. Thank you ever so much for your opinion," he finally said, after a few tense seconds. At least glaring at someone else meant that he didn't have to look at that absolutely ridiculous Darcy Lewis with her absolutely not hot horns that were conjured onto her forehead. Loki thought about breaking the mirror and force feeding that fellow the shards of broken glass, but his fleeting dream of blood and torment were interrupted by the arrival of waffles.
Just as well, since that meant he could stare at them, instead. With a very Asgardian scowl, because this food looked just as ridiculous as he had decided Darcy was.
"Very well. Waffles. These look unimpressive, much like you do."
So there. Looking like he knew exactly what he was doing, Loki took up the fork and knife in each hand and started to cut into some waffle. Without butter, syrup, or any other thing that was supposed to go on it.
