"Oh, I see. Newly arrived in the past, or am I just blind?" he asked with a friendly smile. He took the offered hand and gave it a shake of greeting as she started to introduce herself.
And then it clicked, and Bobby used the hand he was holding to pull her into an excited hug. "Oh my GOD, you're Sean's sister!" he exclaimed, giving her a tight squeeze for a moment before pulling back to grin widely at her. "Hello! It's so good to meet you in person, too," he told her. "Oh my God, I'd have put my nicest suit on and brushed my bloody hair if I'd known - I'm probably getting paint on you, sorry!" he babbled excitedly.
