You must be referring to Clarice (Colorhead) and Miata. Miata is or was the current #4, a child prodigy, she is very unstable mentally and emotionally. Clarice was assigned to be what is essentially her wet nurse and mother figure. Yes, this new story arc could prove to be interesting, what with all of the awakened beings now coming out of the woods and Priscilla reemerging from the Clare-Luciela-Rafaela amalgamation. Have a seat every one and enjoy the read!
On a side note: I attended AX 2012 this week end and did not see a single Claymore related cosplay! Ladies! We need to see warriors represented on the left coast!
