Toby started trying to tickle Nathan, Simon and Monty with unabashed glee. He knew that Peter wasn't there anymore, but his family wasn't just Peter now, it was Nathan and Heidi and the boys and Peter and Sarah...the list went on and on to even include people on the outside like Angela and the other residents of the Hyperion as well. Family. His family was more large now than it had even been back at home. He really didn't care about labels, because the most important label was certainly family, but that wasn't to say that he was anything less than thrilled about calling Peter his brother.
"Saraaaah!!!!" he called, laughing as he jabbed his fingers at Monty's ribs. "C'mere! Your turn!" He didn't care that Sarah was having slightly more dignified grown up congratulations, or that she was near the slightly scary matriarch of the Petrelli clan, he just wanted to express the glee he had at the good news with Sarah in a way he had not been able to since Peter confided the good news.
