For Dr. Llewellyn, there's not an Operator that resembles Alice yet - and she didn't have anyone assigned as personal guards so it prompted her to arrange Ash and Oda for those roles. After some time and the occassional self-doubting at 3am, the Lupo got the duo to take on further secretarial duties so that she will have an easier time processing the Rhodes Island that she woke up to.

Now before those two joined, Dr. Llewellyn's first ever assistant was Lappland - a fellow Lupo like her, despite their differing humor styles and backgrounds. If anything, Llewellyn doesn't mind putting up with the other Lupo's antics.
