[X] Bartolomeo Joins (and pays back his debt to Nami)
[X] Tashigi joins (Not so terribly willingly, but she'll get over it)
[X] Garp catches up, but only once we're on the ship. Now we're wanted for kidnapping a Vice Admiral!
Garp catching up is just too amusing to me to pass up. Plus, we're not technically pirates yet. I mean, sure Luffy keeps shouting to anyone who asks(and anyone who doesn't) that he's going to be the pirate king. I don't think just saying that is illegal, and Garp won't do anymore than try to convince Luffy that he shouldn't be a pirate. If Luffy just saying that is enough for Garp to haul him in or otherwise hinder him, Luffy never would have been able to leave his home. And, if Garp catches up we might be able to get away with kidnapping inviting Tashigi to join our crew, since we might be able to convince Garp to 'reassign' Tashigi to our crew. Besides, it's not like Garp couldn't just leave after catching up with his grandson and his crew.
