Riddel reaches his hand out towards the man's. As he grips it, a tingling sensation, almost like a mini-shock, shoots through his entire body. The wings underneath his oversized clothes move a bit, but he manages to suppress a gasp and prevent his hidden feathers from fully extending.
"U-Um, thank you, sir," Riddel responds politely. "And if you don't mind me being frank, this is the first handshake I've had in a very long time, so..."
He begins looking at the crew. They were cautious of him being a part- and rightfully so- but they all had something unique about them. Maybe they wouldn't desert him, or betray him, or ignore him. Maybe they would accept him, befriend him, and possibly one of them will... will...
Riddel doesn't realize he's daydreaming, and is still gripping the man's hand.
