[Other] How can i put a PC in a Map?

[Lunos]

Hi.
I'm pretty newbie when talking about ROM Hacks, i mean, i've played a lot of them but just now i'm starting to learn some things (Like the msgbox script, the givepokemon script, etc) and now i just wanted to know:
How can i put a PC in a Map, for example, Selphy's House in Four Island?
I thought it would be as easy as copy the Script Offset of one of them since they all work the same, and then create a new "person" in Selphy's House with the PC Script Offeset as his own, but i've found that in A-Map, you can't see the PCs Script at opposite of the warps or NPCs :/ ...
Thank you in advance and greetings from Uruguay :)

EDIT:
I'm an idiot, i totally forgot to specify in the title, i'm talking about Pokemon Fire Red.

The PC doesn't use an in-game scriptbox, instead, it uses behavior byte 83. (Look in Advance map)
