Sareena doesn't have a connection with Hsu hao though. Sareena didn't leave on good terms with Kia and Jataaka because she was freed soon there after. Maybe in Kia and Jataaka's mind there still allies because they don't know that Sareena was freed from Quan Chi's control, but Sareena clearly joined the Forces of Light and has no intentions of considering Kia and Jatakka allies (characters she actually has a connection towards). And what do people think happened to Noob. It still states that he is unknown. He was sucked into the Soulnado, it exploded along with him (and it shows that it was devastating because the graveyard was destroyed as well), and we never see him again. Sure there are other characters that we haven't seen still but Noob has a reason: All this time he's been dead because of the Soulnado. What do people think happened to him, he teleported? (No proof). If he wanted to teleport, don't you think he would've done it before it exploded and it appears he had no control while in the Soulnado.
He was using Hsu Hao as an example of your broken logic regarding it, we don't know the circumstances overall of Sareena's relationship with Kia and Jataka after she was freed from Quan Chi's control, so listing them as enemies actually implicates shit broke out, which has never been given otherwise, thus they're still listed as her allies.
