Father? Well that would explain why this dashing young man looked so familiar...
But clownfish. Clownfish, clownfish... clownfish... ...
Ah, clownfish. Son. What was his name?
"TRITON," his voice said automatically, and his arms were wrapped around behind Triton's back, embracing the boy who was now quite the grown man before the name actually registered in his head. Triton - that's right.
"It's good to finally see you in the flesh," Poseidon added, rubbing Triton's back a little before - hesitantly, he might add - releasing him.
"Come in, come in. Make yourself at home."
Hard to believe that this was his son. Grown up so much, looked so different - but they all looked a little different to how Poseidon thought he remembered them.
