His first instinct is to keep searching while his brother and companions guard the rear, but... "IF'N WE HEAD BACK NOW, WE MIGHT BE ABLE TA AMBUSH THEM!" He repeatedly points back with a gloved hand to make his meaning clearer, already trotting that way himself: if nothing else it'll be quieter back there!
