The small humans may have been spotted, but Bon will make sure that they'll safely be escorted to Twilight. She still didn't like the fact that they were hiding inside of her house during the middle of her mission preparedness for the next day. She didn't feel like carrying them in her hand so she just decided to dump them "elsewhere" for carrying. Most of the girls in Equestria will do this to smaller males and even other females. This includes sibling bonds like brothers that have the attractive sister types, but no true sexual relationship between them, even though most of the brothers won't mind at all being dommed by their sisters.

Not only are the humans going for a very comfy ride between the large baggage, but looks like Checker has also ended up in the home of Bons. Checker is a veteran at this and has been ending up in these situations way before the shrunken humans arrived. Bon already knowing who he is and being the same species won't be taking him to Twilight, but will lecture him while he's riding along with them which will have no affect on him as he'll end up doing this again.
