Just an idea I had after watching Alit's debut episode. Gilag didn't recognize Alit, so why should they recognize Dumon?
Dumon walked through a portal to the front of the BARian. He frowned at Gilag's choice for a hideout because it was so obvious. It had their species name on a bright, red, neon sign for crying out loud! But at least it was easy for him to find. Dumon sighed and teleported into the living room. He saw Misael resting on the couch, that was understandable since he had been the one who was keeping the others out of the way of human authorities and making sure they had everything they needed. Alit was doing push-ups. Dumon smiled, at least that was normal. But Gilag was watching a shining box with great concentration. Dumon walked over a peered at the screen. There was a picture of a human girl with pink hair singing something. Dumon was extremely surprised. GILAG was so interested in that? Apparently he didn't know everything about him. Misael opened his eyes for a moment, gave a little jump, then fell off the couch and on the floor. Alit and Gilag turned around and noticed Dumon. 'Well, took them long enough.' Dumon thought while he waited for them to greet him. Unfortunately, that didn't happen.
"Who are you and how did you get in here?" Gilag snapped.
Dumon was surprised at Gilag's behavior for the second time that day. Gilag was never this aggressive towards him. But before he could wonder more at his comrade's behavior, Misael shocked him even more.
"What do you want? Get out now before I make you!" Misael growled and took up a fighting stance.
Now Dumon was getting confused and hurt. Why was Misael acting like this? Dumon hadn't done anything mean to him, as far as he knew. But here was Misael treating him like a, like an enemy.
"Now both of you calm down. He probably just wandered in by accident." Alit soothed the others.
Dumon frowned. "I didn't come here by accident, Alit. Now could someone tell me what's going on?!"
Alit looked surprised and the other two looked even more aggressive. "Ho-how do you know my name?" Alit asked.
Dumon paused and thought for a moment. He had known Alit and the other emperors all his life, so why would Alit ask him how he knew his name? Suddenly, it all clicked.
"You don't recognize me, do you?" Dumon asked.
Misael sneered. "Of course not! I pay no attention to some random human."
"I'm going to ignore that comment, Misael." Dumon said but this time made his eyes glow red. The others looked shocked for a moment, then Misael's eyes widened in a look of incredulity.
"Dumon?" Misael asked cautiously. When Dumon gave a slight nod, Misael looked horrified. "Oh my god... I am so sorry! I should have realized-"
Dumon held up a hand to silence him. "It's alright. I was confused at first but I suppose I should have made clear who I was before assuming you all would know my human form."
"Yeah! I mean, we didn't expect you to look like a nerdy kid with glasses-" Alit started but was cut off when Misael blasted him. Dumon rolled his eyes and tried to pacify the now furious Alit. Life went back to semi-normal but Misael didn't stop apologizing to Dumon for a week.
