Archer finally looks to where her Master is waving, and...there. That was...

...two little girls? She dismisses the surprise quickly. Hayate is proof enough that Masters can be very young, and there is of course the Berserker she knows so well. Even if there wasn't precedence, the pressure is undoubtedly coming from one of those two girls Hayate's age.

Archer stops pushing Hayate forward, shifting her weight subtly. Fighting here would be a disaster, but she prepares her mind anyway. Hayate's safety is her one and only absolute priority, and she prepares for several contingencies to get her out of here and out of the potential line of fire.
