The potions they had been giving to Sir Alix were strong, and the healing magic he was subjected to made him tired. Those two things combined were enough to keep him asleep well into each day.
At least he was awake, though, that was all that mattered.
However, that also meant that Irene couldn't just appear at Katerina's house whenever she wanted to. She was going to wait for someone to summon her so that she would know the knight was awake and it was her turn to visit.
While there was a lull in her day and it wasn't her turn to patrol along the forest's edge to see if monsters had returned to the area, Irene decided that she would see if there was something interesting she could buy for the knight.
While she had brought along her Volna first aid kit, it was more for wound care and fast fixes. What Sir Alix needed was healing from the inside out.
