Testament has never been to a slumber party before. The prospect both intrigued and excited the Gear enough that they decided attend. It being a celebration for Rose was also a large contributing factor, of course.

Things some might see as mundane are the reverse to one such as Testament, who brushed shoulders with both the dire and extraordinary (willingly or otherwise) for most of their lifetime. They arrive in their chosen outfit and happily mingle in their quiet way amongst the various guests for a while. They ultimately drift towards Rose when they spot her available, offering a dramatic bow. "And there is our most dazzling birthday girl herself. I do hope you are having a wonderful time. The night is young, nonetheless." They tilt their head slightly to one side, flashing a more obvious smirk than Rose might be used to. Testament's makeup is also far more dramatic than their usual on this particular night- their eyeshadow is different shades of red blending into golds, and their eyeliner spreads into thick, shapely (and perfect) wings.

"What was the norm for these events on your Earth? I must say the crowds I ran with in my more social days didn't do anything quite like this "

Okay, the thought of Sacred Knights having a slumber party is pretty funny, though.
