They panicked
They both panicked at their respective realization moments.
He, when he realized he didn´t love C, and calmed down when he figured out who he did love instead.
She, when she finally admitted what she had been denying for years, what she really felt for him.
He fell first.
I´m not sure who fell harder.
All I know for sure is that neither of them liked what they learned from their respective Eureka moments.
S4, save us!
