Suzanne's words instantly made their way up to Yoze's eyes as he followed her instructions. Since Suzanne and Gilan are still in the positions that they were previously in, it wasn't difficult for him to guess where Suzanne's eyes were and thinned the spot.
Even though this would decrease the defensive capabilities of this spot of blood armor, he was confident that he would be able to defend it in case of emergencies. Plus, he would always send Suzanne a message and tell her to use her blood to add additional protection.
In any case, Yoze wanted to use Suzanne as an extra pair of eyes for him to prevent him from being ambushed again...or at least look out for some oddities.
Noticing how fast Yoze took in her message and immediately took action, Suzanne's shock at Yoze deepened as the control of his blood was quite high. It was much better than hers and had reached the level on par with a Peak Blood Master.
