Basically, it's what Haruka said to him: "You're still you. You're still Kanata." It may take time, but if he faced the same trials while being helped by Haruka and Towa, he'll go along the same track. Of course, by now it's already too late, what with him telling someone to give up on their dreams.
Now, I don't think that's what'll happen at all. He'll get back his memories at some point, but then how he deals with the hurtful things he said is another story. Towa went through the same thing about making amends for her sins. I'm guessing by the next episode preview that Towa, Yui, Minami, and Kirara will be the ones to help Haruka recover, but that doesn't mean it'll change the current Kanata's mind about it being too dangerous. I also don't believe that the cursed vine plot will be resolved all at once next episode, and will lead to more between them all.
