Oh yeah? You seriously believe in originshipping? the only evidence is steven staying ouside of a cave with wallace because he was supposobely (sorry, bad speller) "trying to comfort him". I don't even think they ever meet in the anime
Ahahaha you haven't read the manga have you.
Steven, knowing he is going to die in the upcoming battle with the Regis, turns the title of Hoenn Champion over to Wallace. Wallace had won the title originally, but gave it up to Steven to be with Winona (his then girlfriend). So Wallace is like 'I can't take this.' and Steven's like 'Wallace, please trust me.' And Wallace does, just as Steven trusts him with his former duty. So they're obviously good friends. Besides, there are many times when Steven grabs Wallace to get him out of harms way and doesn't immediately let go of him. And you might think that means nothing but you have to see the scans. Platonic friends don't hold each other like that. Right before Steven dies, they're leaning on each other.
Throughout the arc, Wallace seems to be getting over Winona, who recently dumped him.
This stops when Steven dies. Wallace absolutely refuses to leave Steven's body in the cave and even commands his Metagross, which means that Metagross either knows and trusts him or knows his trainer would trust him, meaning they spend a lot of time together. Of course Steven later comes back to life (thx Celebi) because this is a kid's series and they don't kill people off, but before that, when Wallace faces Magma and Aqua, he is ****ing pissed at them, because they caused this and killed his friend, a friend that trusted him more than anyone. And later, he lets go of his ties to Winona and they stay friends, although Gracefulshipping is still a realistic possibility. But I don't like it much.
In the games, every time you call Wallace all he talks about is Steven, what he likes, how he acts, etc. And in RS, when Steven goes offscreen to get Wallace and you follow him, when you see him talking to Wallace he's like '!' and turns around fast and is suddenly all formal with you. ;)
You can interpret this however you want but the ship is quite possible.
