@Darkmint13 Ostensibly, but it's been revealed that Ezekiel had no romantic feelings for her, and it has also been hinted that his father was probably the one to push them together. In any case, we've had no indication that Jeanette is actually romantically attracted to him. She was probably just plain ol' hurt at his words, which anyone would be.
Also, they've grown up together since they were basically toddlers, so the whole idea that they would be romantically involved is just weird to me.
@petra Yes it came out of left field, I guess he was just annoyed at being lumped together with Jeanette in regards to being "just friends" with Athy or something, I dunno. Bad move all around.
