That was more than enough for Xena/ Gabrielle...
(Moiraine/ Siuan book is entirely read-between-the-lines, as is the case with much of Jordan's stuff. Oddly enough Sanderson was a lot more direct despite being a Mormon. Partly that's due to the limited perspectives employed, ie Rand is a pretty conservative country bumpkin type who assumes two women he disturbs are plotting something when it's pretty obvious they were euphemistically 'plotting' 'something' and doesn't question why an important noble has never got married. You had a lot of aes sedai commenting about how close M/S were as novices/ accepted though, and inferences that a sexual relationship was believed, by them, to have been part of it. They were common enough that the rebel aes sedai ordered, um, Meidani? to resume her relationship with Elaida to spy on her despite it not having been active for, presumably, decades at that point.
Not exactly conclusive, but at least a plausible read which is better than most of the wot s1 alterations were. The relationship continuing into the present though, pure garbage. The book versions would never take such a stupid risk for no advantage)
