Quentin moves out of the gouls' and orcs' way and casts daze on one of the (unoccupied) hostiles that is going after unconscious Hunter or immobile Cambrek (in that priority; if any). (Unless, of course, daze doesn't work on undead. It doesn't specifically say so in the spell description, but maybe undead are immune to mind affecting spells, I dunno. If push comes to shove, Quentin will use wizard's fire instead, if this is more feasible, even if it turns him back visible.) If any team member wants any of the remaining spells cast on them (or Hunter), instead, Quentin will gladly oblige.
Ciela, content with what she has achieved with sneaky planning (that went not exactly as expected) and sheer good luck, goes back to observation duty (or, as KITT would say "surveillance mode" ^^) .
