Hi, sorry to bother, I just wanted to ask if Carl the doggy merchant will be a dateable character? I know he has a bath scene so Im just curious :P

No. As stated in multiple places, the characters in the game's banner (minus Taavi) are the game's dateable characters.

Aah I see, so Macsen, Zhocar and a blue dude we haven't met yet. Will we still have scenes like with Cabotte?
