Even without the enhanced senses of a werewolf, demons stunk like rancid meat or sulfur, all of which unpleasant. If Loki worried about anything it was that there was little to no cover from betwixt the complex. If anything, they were trapped in. Hopefully he and Elsa could put a wall of ice or fire up in case things got really awful.
He marched silently alongside Anna and Elsa, eyes and senses alert as they awaited the status of Isaac's keen sniffer.
