It is what it is and it doesn't seem to have bugged lines/scenes anymore, you just get a few dialogues and that's the "evolution" of Minthara romance, basically applied to some other companions whose romances have almost nothing past Act 1 (sometimes 2).
Nope. It's still bugged. Flags don't work correctly. There is end game cutscene (+couple of dialogues in act 3) and with her but you have to be lucky enough to avoid bugs to see it. You can see some on youtube. In my new playthrough i wasn't lucky enough to see something else except "mind meld" in act2.
