I feel like I should tell you/make a note of when a page is not meant to be funny, but rather, one which is meant to spur the plot along (or be one of the other emotions in the feelings-rainbow). That way you don't have to try and find a joke in a page where there isn't meant to be one.
Reika -- Right you are.
Zoe's Ami -- It's Zoisite making a joke at the expense of Kunzite's sexuality.
Good grief, I hope I don't draw Kunzite + Zoisite similarly enough to get them confused.
