"Sorry mate, but Finn's already taken. That's going to be the name of the baby on the way," Seamus said, winking even though he had no wife at home, two kids, or a baby on the way. "You're stuck with Thomas Thomas. S'what you get for letting me get some poor bird up the duff." Seamus was careful enough not have a couple little mini-Finnigans running around already, but if anyone got anyone else accidentally pregnant, good money would be on the Irish fellow who humped everything that moved.
Seamus knew it too. Which he was why he was quick to kill that particular conversation. "I don't think you would, ye great big softie! And if you did? You won't like what I plan to do to your bed in the Tower," Seamus warned, though he was well aware that Dean would never leave him to fend for himself like that. Not for more than a few minutes to teach him a lesson, anyway.
"And I wouldn't put it pas-HEY!" Seamus cried out, when Dean started to drink without waiting for Seamus to get with the program. Grabbing his pint glass, he knocked it back but Dean had the jump on him and would finish before he could.
