How he got sick

Klavier catches a cold due to wet weather mixed with no umbrella and a clumsy Apollo.
Klavier's stuck with a cold but he knows that he has a Gavinners concert so being the stubborn person he is he goes ignoring Apollos words "DON'T go then".

While practicing for the concert Klavier feels his cold turn into a fever, he tells Daryan that he's fine but obviously he's lying. Showtime hits and Klavier is nowhere near feeling better but he still performs despite his dizziness, nausea, hot sweats and migraine. Halfway through singing the chourous for guilty love Klavier collapses.
