Sorry! Subtitles go kinda quick.keep up if you can! XD
This episode is pretty confusing, but I'll make it clear for you,
Mya had met a new friend which is Tesna. As they get together in the hot tub with Namii, Tesna asks Alex to join in with them because she wanted Alex to be with Mya. So Namii was in on the "plan." Sorry for the confusion! And the next part would be using Sony probably.
