Precap analysis from my perspective

1) Maya is the killer

2) vandana heard Maya talking to herself and imagined the "flashback" scene of Maya killing ashwin. Vandnana assumed that Maya killed ashwin by what she heard.

3) Maya is saying all that to scare Vandnana that she's capable of anything and everything.

4) Maya is protecting the actual killer

What do you guys have to say on this?

Ps: We kind of got a hint today that Arjun will leave Maya at some point.
