The next day.
Although the maid assured Eileen that she was fine after the strange incident by the fountain the previous night, just experiencing a minor malfunction and undergoing routine maintenance, Eileen, still feeling uneasy, ran early in the morning to knock on Renji's door to discuss the matter.
Renji took the matter seriously. After opening the maid's panel and finding no abnormalities, and with Suthia also being around, he took the nun to check on 86.
With Thia's nod, indicating that everything seemed normal with the maid from her perspective as well, Renji finally felt relieved after the double assurance.
Eileen also felt completely at ease. Despite often bickering with the maid, 86 was the closest person to her around Renji. Even at the risk of "disturbing something important" and being unwelcome, she wanted to eliminate any hidden dangers for 86.
