Shouting fills Nightmare's mansion as yells arise . Killer runs through the halls , laughing as Cross and Diamond chase him . Killer nearly trips on the two stolen swords he's holding but manages to get his footing before continuing to run . There's a flutter of wings as Diamond teleports in front of him , knocking Killer back and causing him to drop the swords . " No fair ! " He says with a laugh as Diamond takes the swords back , handing one of them to Cross . " What about your whole thing about not using magic ?! " Killer says , standing up with a grin .
" Exceptions can be made . " Diamond says calmly , though unable to keep himself from cracking a small smile . He folds his large black wings , staying out of arm's reach of Killer just in case Killer decides to get payback for being knocked down . Cross rolls his eyelights with his own smile as he walks away . Diamond turns to leave as well , playfully whacking Killer with an outstretched wing , causing Killer to give chase .

Nightmare listens to all of this from his office silently . Despite the slight sting from the somewhat positivity , he doesn't interfere . Spirits had been so down recently that even Killer wasn't doing his normal shenanigans , so this small break is welcome to all of them . He closes his eyes with a small smile , content to just listen for a bit .
