"Maybe I could tell you some stories, then."

"I'd enjoy that."

"I'll try to think of some good ones."

"I'll wait eagerly."

Nodnod.

And to getting their things together?

Yes; they can work pretty efficiently, including the stop by the alchemy lab, and an early check if Danella will be accompanying them. 

Not right away. She's got some other leads to check out first.

"We'll update you after, then."

"Have fun~!"

"I intend to."

"How're you planning on getting there?"

...Hum.

"Aw, now I'm really curious!"

"Perhaps it isn't my secret to tell."

"A mystery, then. I shall have to hunt for clues."

"I wish you luck."

Her quest is perhaps aided by Birgitta's appearance, fully armored. (For a definition of fully that includes 'wearing a skimpy leather harness that resembles horse tack and a bit gag'.)

"...Huh. That's. Uh. New."

"A rather powerful armor," she comments, eyeing the harness with clear delight. "Where did you find it?"

"This is my normal one. It. Just does this now."

"Another gift then," she says, as she steps closer and runs her fingers over the elements that mark the harness as clearly the Dark Brotherhood's - from the dull red leather framed by black strips, to the red panel with the Brotherhood's hand stitched into it that's currently arranged over her sternum where the tack connects, to the thick black panel on her lower back that resembles a saddle, and the red cloth flowing out from its sides, the black hand emblazoned on either side... And then up to where what would be a cowl on Maellys cradles Birgitta's head with strong strips of leather, reins currently tied to her shoulder pads, and back down to the heavy gloves with their palms hard and metallic, eyeing though not yet touching the boots which when Birgitta isn't making a point of walking silently strike the stone floor with a sound rather like horse shoes. 

Squint.

"...Are you a real horse girl now?"

"A horse girl well dressed for training, at least..."

"Try to remember you're on a job, at least..."
