Pent and Louise are khaethkjshtka adorable.

Also, Pent's supports with Canas? The very definition of adorkable. Seriously.

And yes - as professor_tammi mentioned, Elphin does still have periodic blindness, which doesn't seem to be something anyone can cure. (My headcanon, which I've seen some others theorize about as well, says he eventually goes completely blind. But that's just me.)
