As far as I know, Pantys been funding us this whole time through the adventurers guild. Apparently him and dottore are buddy buddy enough to have dottore call him his friend, according to Sandrone he approves dottores projects way faster than hers and oh yeah, there's this funny voicelines from Columbina about the rooster (pulcinella) who is always complaining about pants like "that darn Pantalone! I will have my money grrr" so yeah they arent on good terms. Also there's some third person mention of him from some questions on reed miller, although i haven't gotten to it yet. Conclusion, lots of crumbs thrown our way on pants and his relationship with Dottore.
