Poseidon is emotional because he is the Sea God. His children get his emotional part from the godly side.

" Poseidon's children take their personalities from his changeable persona. As Sciron is darker and merciless, as a rough and murderous seas, whereas Percy takes his father's kind, soft, and peaceful sea persona."

So I guess Poseidon kinda has the same thing.
