Seth looked around at his surroundings. Lyra's eyes widened. Twilight and Sunset began having a important discussion in hushed whispers and then Seth opened his mouth.
"Excuse me do you have a bathroom?"
Twilight looked up and decided that yes we were not expecting that, no it's fine we can do this. "Second door on your left down the hall over there," Twilight pointed a hoof at the direction that the nearest bathroom was in. And Seth ran down in that direction in a jiffy.
"Huh you think he'd be I don't know confused?" Sunset said a worried expression on her muzzle. "It fine," Twilight said as the sound of flushing a toilet was heard, "just wait for it."
"Wait for wha..." Sunset started but never finish for at that very moment.
"Gggggggggaaaaaaaaaaahhhhhhhhhhhhhhhhh!!!!!"
"Oh..." was all that Sunset managed to say before a loud angry rant could be heard
For purposes of time and to keep things teen rated the FCC has decided to cut out the actual rant and fast forward to the end
Twilight knocked on the door, "You done in there?"
"Yeah.. I guess..."
"Do you want to join us for breakfast?"
"Sure...I guess."
"You realize we heard all that..."
"Um...does it bother you?"
"What does?"
"That my world supposedly depicts yours as fiction?"
"Honestly, it might explain pinkie pie."
"...Lyra put you up to this?"
"Yes."
"You know we're pretty sure you guys are xenophobic."
"I think we're improving."
"Pinkie is coming isn't she?"
"Probably..."
Sunset who had calmly made her way to the door then spoke.
"You coming out?"
Seth came out his long dark hair brushed to the side. He looked at the ponies. "You guys are taller than most people thought actually." He just realized that even with a six foot build, they still came under at just about eye level. Sunset shrugged, "To be fair, we didn't know alicorns weren't the only ones who could do the Canterlot voice."
"Human..." Lyra said almost dazed at the whole experience. Walking over to Seth in a dream like state.
"Seth...my name is Seth."
"By the way...you know how loud the Royal Canterlot voice is?" Sunset asked.
"Louder than what they depicted on television I guess?"
Then they all had a moment of realization. "Guys I think Ponyville knows." Twilight said with a gulp.
