Yeah, I wouldn't mind doing something like a timeskip. It would reduce the possibility of Alexis speaking to ghosts, but maybe we'll have another opportunity for that.
Edit: I'm tempted to have Lewis and Alexis have some sort of thing where they are never seen sleeping, and if asked, Lewis would reply along the lines of 'Chesto berries. Tons of fucking chesto berries' and Alexis replying with 'What's sleep? I'm a plant!' For no reason other than comedy, really. If it can work in some Anime, why not have it work here? Of course you'd expect them to need some form of sleep, but you never see them sleeping, so it would lead to questions over how they haven't collapsed from lack of sleep. Pokemon logic!
Edit 2: I have made my post, we can now do a time skip.
