When Isha first came to Hyrule she often was seen wearing war paint. She didn’t see anything wrong with it since everyone in Skyrim wears war paint even when there’s no battle going to happen.
She changes the paint every now and then so sometimes she won’t be wearing the same war paint. She does this because she looks a hundred times scarier in some war paints than in others
When Urbosa first saw Isha she was alarmed by her war paint but didn’t show her alarm immediately because Isha wasn’t acting aggressive towards any of the locals
Once the two of them were alone Urbosa asked her about it, hoping that this wasn’t the beginning invasion or nothing of the sort.
Isha explained that a lot of people in Skyrim wear war paint even when there’s no battle going to happen.
Isha also prefers to wear clothes from Skyrim, saying ‘They’re better armored’
Ever since Link found out about her lycanthropy he made it his mission to understand her ’gift’ better, so he can be a better husband.
When the full moon comes around again and Isha doesn't have Sapphire to make the amuletthe two of them go somewhere even more secluded to bring the chances of Isha hurting someone down as low as possible (even though it was already really low, to begin with) while she's in her wolf form.
Isha brings Link to Skyrim once a year for at least a week every year. 
They also help some of the people of Skyrim when they’re there and have earned a reputation for being heroes
Because of this a lot of women and some men flirt with Link even though they know he's married and Isha gets very territorial of her mate
Link doesn't mind one bit when Isha gets  territorial of him around those flirting with him as he knows she can't help it.
What he doesn't know is that Isha secretly fears that he’ll get tired of her constantly hovering over him when she feels like someone is trying to ’replace’ her and leave her.
