Percy Jackson- Why didn’t Chiron move Chris into the Sick Rooms when it was clear he wasn’t mentally well?

Chiron and Quintus allowed Chris to come back to camp as he would have been put into a mental hospital as Minos had messed with his mind so much. They knew Chris wasn’t well but they allowed Clarisse to care for him even though Chris was getting worse and hiding in the basement, then when Percy came back to camp after being in the labyrinth, Chiron told him that Chris was almost dying and they had (finally!) moved him into the Sick Rooms as he had given up on life. Everything was ok as Dionysus pitied Chris and wanted to give him a second chance and healed him but if it wasn’t for Dionysus then Chris would have died. Why did Chiron leave it for so long? Do you thing Chiron didn’t really care for Chris had he went over to the bad side?
