Kyran was too absorbed in teaching Oded and Yalen his concoction method that he did not notice people watching them from the medication room's two-way mirror.
Apart from Cyneah and Nahir, Azikh, Gidan, and the matron also went to the infirmary.
Nahir initially wanted to enter the medication room, but Cyneah stopped him after noticing Kyran, Oded, and Yalen were in the midst of concocting potions and pills.
If they entered while the concoction was ongoing, there was a high chance they would contaminate the air inside the medication room, affecting the efficacy of the herbs still on the table.
Because of this, they settled in watching the three and waited until they were done before calling Kyran over.
