Ben just sort of stares at Nihlus's hand for a moment - is that not a thing they do? - before taking hold of it awkwardly in something resembling a handshake.

Then he realizes he was kind of... misunderstood when introducing himself. Crud. "No, actually, it's just, uh-" He points at himself. "Ben." Then at the alien. "Nihlus Kryik?"

If Nihlus's pronunciation is sort of off, Ben's is an absolute travesty. He's trying, okay.
