I'm disappointed those other episode titles proved to be fake, but I'll wait until we get more information on this episode before I make any judgment calls. Given SM's trend of having major events happen in episodes whose titles made them seem like filler, who knows what might happen in this episode? It could turn out to be a very plot-important episode.
Guessing this will be another Lillie episode where she'll be able to touch another pokemon besides Vulpix since she takes care of Pikachu.
I really like that idea, and while I'm not going to get my hopes up until we have an episode summary, I want this to happen, because this could potentially be excellent character development for Lillie, especially if she is able to touch Pikachu by the end of the episode.
That does beg the question of what is keeping Ash from taking care of Pikachu himself. Perhaps both Ash
and Pikachu are sick, and Professor Kukui is occupied and can't take care of them himself (perhaps he was called away to help his fellow researchers again), so Lillie (or one of Ash's other friends) volunteers to take care of Pikachu while Ash is ill. Perhaps Pikachu can't be left alone in his illness, because he has become delirious and is at the risk of running away.
'Taking care of Pikachu' suggests that this episode will most probably be a 'Pikachu getting sick' or 'Pikachu focused' filler, with no plot progression.
A suggestion is not a definitive. You really have no way of knowing what this episode is about. As I said above, with the SM anime's trend of having major events happen in episodes that appeared to be filler by their titles alone, I wouldn't be surprised if something plot-relevant ends up happening in this episode.
