"..."Kruger takes deep breaths to calm down. Having seen Cattleya in such a bloodied state had stirred him towards negative thoughts and emotions he wish not to act upon.
After he opened his eyes again, he notices that Professor Ramsay is already helping her via this peculiar automaton. That should be enough for now, scolding her can happen at a later date.
Out of the corners of his eyes, he saw Arnett taking his retreat. While they haven't really interacted with, Kruger feels like he understood better who the younger Sokolov was, if just a little bit. Of course, Orrel has forbidden him from approaching his brother, but little did he know...
... Kruger does not need to approach people in the first place.
He holds a hand before his mouth, to feign contemplation, while focusing on his unique Arte organ and moving his lips. No audible sound escapes his lips. But a whisper reaches Arnett's ears nonetheless, as if Kruger stood directly in front of him.
"You braved the vines to heal someone else. That requires courage. My opinion of you has improved significantly since the field test. I am proud of you, and even if he is not showing it right now, your brother is most likely proud of you too. That is all, you may leave now if that makes you feel more comfortable."Then he ends displacing his voice, but he still holds his hand in front of his mouth. A necessity, since displacing is voice is much, much more straining than amplifying and spatially limiting his voice, especially when so many words are used. He wanted to make sure he wasn't coughing blood like the first few times he spoke several words while displacing.
After making sure, he lowered his hand and looked at the class as a whole.
