Tower disaster!/Brian runs away

This is how the tower disaster occurs and where Brian runs away in Revenge of the Nightmare Family & Changling Queen

[2 days later, Brian is now out of the hospital and soon he drives back to Cantetlot, and as he walks into the main hall, everything is higher in progress]

Brian: Wow. Things have really gotten better in here, with my lead everything will be done in no time. It's been only 2 days.

[then he finds the Royals who are with Thomas]

Brian: Guys, what's up?
