Jane was fighting to get to know Kai when she first joined their unit. Desi (their smithy) had to tell her when she first joined that she'd likely have a lot of difficulty getting more than his name and she took that to heart
She was following him everywhere and asking him every question under the sun. He tried so hard to ignore her or brush her off but gog she's so stubborn
The first time she succeeded was because she decided to just pull open her shirt and he very quickly was pulling it shut. She was giggling and teasing him because "of course that got your attention hehe pervertttt"
Blazej (their handler) and Desi had to just watch as Jane tormented Kai and dragged him around because she was determined to learn about him
When Jane first met Mina she told her she didn't have a name and Kai very quickly went "I thought the others called you Jane Doe. Is that not your name?" And she got so giddy that she immediately agreed. Mina thought they were dating (girl just you wait)
She still teases him about how closed off he was. Mina joins in all the time. Poor man is sitting there with his head in his hands as his girlfriends pick on him
