If they'd been inside, in a room or even in a hallway where there were only so many directions danger could come from, the ninja would have shrugged off the offer of assistance in favor of moving onward. He knew how to handle his own injuries. Being outside however, and in an unfamiliar location had him choosing to let Tsubaki do what she would without any protest. She was stubborn, same as him, and getting frustrated at each other because he wouldn't let her help would only waste time and likely let the birds know their location.

With Tsubaki and Sora both agreeing to head back to the institute, Kurogane's thoughts went to what others were thinking. Most were probably thinking the same - that the institute offered some form of safety. And chances were that Landel was counting on that being the case.

"He set this up. That doctor," Kurogane stated through gritted teeth while Tsubaki did a better job than him of seeing to his injuries. His eyes wandering back towards the road as he added, "If we're heading for the Institute, be prepared for a trap. Both along the way and inside."
