Reigning in the hot-headed idiot isn't exactly something exclusive to Mavis.

This chapter reminded me more of the infiltration of Everloo mansion, long before Mavis first appeared. There Lucy also managed to convince Natsu to sneak in, when he wanted to bust the front-door down. Only this time Natsu messed the sneaking up, instead of them being shown on survailance Lacrima.
