Pallet Town | Morning
Phobos doesn't feel like anyone here knows what they should do. Up until these strangers showed up and Shadowmere ran away, things had been mostly clear-cut. Sure, there'd been a bunch of freaky things going on, and the one exception where Shadowmere panicked the first time...but this is different. This could be life-or-death. In some sick form of irony, that sort of thing tended to breed indecision. Phobos knows that way too well.
"Maybe... But if he's her father, then parents often do... almost anything for their children."
Did they? His own parents were never around that often, and Father had turned on him and Deimos as soon as Mother faded away. Would either of them have done 'anything' for Phobos? He didn't want to think about the answer. It wasn't like they really saw themselves as his "parents", and he'd only picked up on the "mother and father" thing from observing other Pokemon, anyways...
But maybe corporeal beings are different, and the bonds between them stronger. His own parents expected Phobos and Deimos to be able to take care of themselves. Maybe that was why Father never interfered even when he knew one of his children was tormenting the other. If weak little Phobos couldn't defend himself, then obviously he deserved it.
"For now... Let's hide. I'm not sure if I trust them yet."
Phobos floats along after them, seeing no reason to object. He's good at hiding. That's pretty much all he's ever done. Fighting, on the other hand, has always been a rather horrifying experience, if you could even call it 'fighting'. In his mind's eye, he can still see those Pokemon his sibling would force him to attack. Better for nobody to be hurt than to see that again.
Once inside the house, Phobos doesn't know where to go. He can see Oliver going to one of the rooms, the one without any ugly stuff inside of it, but the little ghost is hesitant to follow. Going after him would probably make him look creepy, or maybe they'd think he's like a scared, lost kid. Neither of these sound very appealing.
Still, would either of them really care what he did in here as long as Phobos stayed out of sight from the strangers that might still be outside?
