Confused

Can some1 plz explain this last part

"Nitya meets Pammi saying if not for Bauji stopping her from leaving the house she would've ruined her plan. She tells her that she's still in love with Kavya and the only reason she's supporting her is because she has no other choice and the moment she gets a chance she'll ditch her (nity). She thanks her for doing her a favour by separating Yug and Anjali and leaves.

As she leaves, Vayu is waiting for her and tells her that he knows exactly what she's up to".

yet to see the epi
tell u later 😳

well i'm not sure excatly what to interpret but here is whta i understood
if pammi left tthen k and a would get a chance to unite. therefore nity says that pammi would have ruined her(nity's) plan if she left.

thus nity has no choice but to support pammi.
well i don't know why vayu said that 😕
but i hope this clears ur doubt
