We’re still here, Fearless, don’t worry.
Leo copes with residual, morbid fear following the fungus incident. Donnie believes it is because he was hit with spores multiple times that the fungus’ effects upon his mind have not yet dissipated entirely. He becomes anxious whenever his brothers are not near, and struggles to even meditate alone without being plagued by visions of them disappearing. Luckily, his brothers pick up on his anxiety, and start going out of their way to just remind him that they’re still there.
