While the tear gas was certainly a nuisance as it began to drift out of the grenade, Vergil had been through far, far worse on Rex's campaigns, and had endured greater torture than a little burning of the eyes and tears streaking down his face. While it would be a hindrance for sure, Vergil knew it wouldn't be a major stumbling block.
He was below Emilena, trying to hold in his breath and avoid from choking on the gas. He had to keep low, but he also knew keeping stationary was the best thing during a gas attack; the wind would soon blow the gas over and beyond them, so staying still was the best bet in times when there was even a slight breeze, which there was this day; gas attacks were far more effective indoors after all.
Waiting it out patiently, the gecko closed his eyes, even as he felt Emilena fall to the ground somewhere off to his left, and the snapping of what sounded like a gruesome bear trap going off. Cringing, he fumbled his way through the now dissipating gas to where Emilena was struggling with a trap that had seized her tail. The cloud had drifted more toward her, so Vergil was crawling back into it, but he dealt with it as he kept his head low, and began pushing on one of the springs to release the trap enough for the fox to free her tail. "Go!" he urged, pressing it down. "And try to stay stationary... the gas will be over us soon!" he whispered heavily, the fumes stinging his tongue as he spoke.
Tony noticed the road had to be taking him back to somewhere around the castle. He was heading in what he thought was the general direction, and was cruising along at a leisurely 40 mph, not wanting to come up on the castle without warning and risk getting shot at again. As it was though, his path was taking him closer to where Emilena and Vergil had run into the woods, though he wasn't close enough yet to see the tear gas through the trees.
But someone else was close by now as well: Stryker had left the castle and was heading into the woods. With no way of being able to track the escaped targets, the sungazer lizard figured he'd murder William first, then hunt down the other two, who would be too badly injured to move far. He was decked out in forest camo gear, his body painted thanks to a device they had in the castle, and his gear reflecting the shades and shadows of the nearby wood. Besides... his two targets would be making for these woods eventually... and since there was only his Cord in the parking lot, he knew they hadn't taken that, as it was still sitting safely in its spot.
Having retrieved a high-tech sniper rifle from the trunk, the lizard was also carrying combat knives, throwing knives, his laser pistol, and flashbangs. He also had a handy set of goggles that would allow him to track William's trail through the forest... but as it turned out, he also picked up a good deal of blood on the leaves, so he knew William was hunting them. Very well... perhaps they could pool their efforts... or of course let William take care of it, then shoot William after he was done. There was no way Stryker was being denied his revenge after all...
Right before the sungazer disappeared into the treeline, Tony just barely made him out as he approached the castle from the rear. He slowed the Duesenberg, and narrowed his eyes. Stryker heading into the woods fully dressed in combat gear? Had Emilena escaped? Finding no other explanation for the lizard's behavior, Tony decided to pull over to the side of the road. Shutting the Dusey down, he exited the car, tentatively reaching for the Glock in his waistband.
Pulling the pistol out, Tony began approaching Stryker at a right angle, but paused when he saw the lizard wearing some sort of goggles. Trackers most likely... the ferret stood stock still, waiting for the lizard to pass ahead of him before he slowly started following, but even then waited until Stryker had advanced quite a ways ahead of him. No sense giving himself away too soon...
