For the statements that help us to support our shipping a little bit more.
So, do post your quotes in canon that you find shippy, but for clarity and convenience, just make sure to have...
1. Who said it (to whom if you really want).
2. Depending on the media...
Game: Version, Event (i.e after you got the X badge, etc), Location, Game.
Anime: Version (as in, original Japanese or dub. If dub, which one), Episode, Series.
Manga: Version, Page, Chapter, Volume.
3. What shipping it relates to in your view.
Also, an explanation as to why you think it does. So, for example:
"My heart was racing when I thought Shuu-sama was watching." - Brianna in the Original, AG162, Advanced Generation, Admirationshipping.
I feel this quote conveys Admirationshipping from Brianna, after she finishes her appeal round and confides this to May. It is pretty clear that Brianna is, at the very least, infatuated with Drew, by her blushing, nervousness around him, and her statements, such as this one. Her heart was racing, and when she says this, she blushes, so it can be seen as romantic feeling of wishing to prove yourself to someone you respect (shown by the -sama honorific, which is reiterated by "Mister" in the American dub) very much.
Note: The quotes are a matter of perspective. Please refrain from trying to belittle someone's quote because you disagree. Hopefully, the explanation will help make it more solid. And, no, it doesn't have to be as obvious as mine. XD
