Firm nod. "I will. It is the duty of all handmaidens to contribute to Our whole."

"I will be in your care, handmaiden."

There's almost a smile in her voice. "I will take good care of you, handmaiden."

When do they start?

As soon as he's ready. 

He's ready now.

Good.

The first matter of business is getting him oriented to the estate on Naboo from her perspective, and to the traditional duties and expectations of a handmaiden...

Of note: he may be addressed as handmaiden as a candidate, but he is not formally a handmaiden until he takes the mask and identity of one, which requires a good bit of training and ceremony. (The training mostly ensures that the candidate understands the true meaning of what she will become, what she will give up.)

He's a diligent student.

(This is probably the first time he's actively wanted and pursued something since joining Sidious's service.)

(She very much approves, and lets him know as such - as Sidious, sure, but as a fellow handmaiden more than that. All of the handmaidens are honored to have him joining, Lylí included.)

Oh, that's so good.

"Do you enjoy your training, handmaiden?"

"I do."

They're in the inner chambers of the estate, now, so she slips her mask off and sets it by her desk.

"Good."

"You know, I don't think it'll take much longer for you to be ready to take up our mask."

"Really?"

Excite.

"Really."

"You've blossomed here."

"I've- had good teachers."

"That matters a lot."

"Salí's going to be the main one evaluating when you're ready, but - she's impressed, and I've never seen that before." (Salí has been quite the taskmaster in teaching Maul how to run an estate. No one's saying that her previous self was military, but her previous self was definitely military.)

"How many of the handmaidens were inducted after her?"

"All of them - except me, of course."

"Oh."

"You're a rare sort, handmaiden."

"I do my best."

"I know."

"You make me the best."

Heeeeeee.

"You make it easy."
