Well, that’s hardly suspicious. “… All right, then. Ready to go?” Ingo turned to leave fairly quickly, hardly giving Emmet time to reply. What was he going to do now? He’d been looking forward to that break… But with Emmet’s persistence, Ingo didn’t have much of a choice whether he protested or not.

“Yup!” Despite his brother’s obvious discontent, Emmet seemed to remain oblivious to it, and followed behind his black-clad brother in his own joy. Honest, he was only curious to know how brother spent his time while the train was resting in the station between trips. That was all!
“… All right. Fine. But why do you ask? I’m only going to walk around the station. You never seemed particularly interested in joining me, anyway. Where did the sudden interest come from?”

“Yay! Thank you brother.” At the following question, Emmet simple rocked back on his heels and shrugged; as if he had little motive in the sudden desire to tail his older twin.
subwaymaestro replied to your post: “Brother! It’s almost time for break! Can I go with you this time? Ple—ase brother?”
“Not really. I just thought it would be fun! Brother never lets me come with him.” Willfollowyounomatterwhatyousay—
“… I don’t really do anything interesting on my walks, Emmet. I’m sure you would just be bored.”

“Brother. I won’t be bored! I’ll be good. I promise.” whiiiiiiiiiiine

“This is fun! Are we dancing? But we need music to dance. We should get some!”

“On? But Emmet is not a train. I don’t have an on switch— Oh! Well maybe… Big brother! He wakes me up in the morning. That’s ‘on’. More or less.”

“Oh. That’s easy! What else are showers good for?”
“Oh no! Um—”

“Boo!!”

“Wait, that’s hiccups isn’t it…”

“That’s okay! I’ll sleep in big brother’s room tonight!”
