This thought came to mind after I read this forum post XD
In a jokingly way of course
Hmm wellllll, if Stella and I met..it'd probably be like this [ I also consider her to be myself XD ]
Me: Hi, Stella! It's nice to meet you! Wooooow..your eyes are even trippier in real- life! ...I want them..
Stella: E-eh?! Uhm...wh...who are you...?
Me: Hmm? Oh! Sorry, I was staring at your eyes..so...tri-Anyway! To sum it all up I'm kinda you, Stella.
Stella: Y-you're me? N..no no, that's not possible! You simply can't be me!
Me: Oh, but I am! Ask me a question, annnny question~!
Stella: Wh...where am I from?
Me: Ithania...
Stella: ...uhm...y..yeah.
Me: Yooouuuuu also have a strong bond with your sister Rachel, much stronger then your other sisters, not mentioning your pa- I mean well you cry. A lot..
Stella: ...H..how..?
Me: I told you Stella, I'm pretty much you...Because I created you.

Rosalyn and I
Me: Good evening Rosalyn~
Rosalyn: Hello...
Me: Showing off your boots you love so much as usual eh?
Rosalyn: ...Yes....who are you?
Me: The creator of your looks and personality..
Rosalyn: Pfft really by /you/? Are you even of any riches?
Me: I'm of the most important riches, which are none of your concern.
Rosalyn: Heh...of /course/ you are.
Me: Hahaha, oh Rose, you better stop while the gittin is good. Got it?
Rosalyn: Is that a threat?
Me: It could be, then again it could be not. You're a smart girl../you/ figure it out!
Rosalyn: Excuse me! But I'll have you know that my brother is a-
Me: Yeah a guard, I know this. Anything else you wish to point out?
Rosalyn: Ugh! I am of riches! Not a creation of something like /you/!
Me: Well too bad, you are. Now get over it, you spoiled-rotten brat!
But seriously...If I SAW one of my characters [Especially Stella..] I would for sure squeal and jump around, spazzing about, then proceeding to probably smack myself a few times in the face, after gawking for a couple minutes, just to make sure all of it was reality and not a dream. If I were to approach my characters I'd have a shy approach at first, being uncomfortable and all. But that's ok cause the more I'd talk to them the more I'd get comfortable....except Rosalyn...Id...Id probably erm..well..Id want to smack her...hard...in the face...with my fists.
