I really trust and believe in her instincts when it comes to Dev...
I mean before she would sumtimes misunderstand him (like how he was trying to keep her away by seducing her in the hotel room 😆), but now that she knows he loves her, I feel like her love is so much more powerful that it gives her something like a sixth sense... 😉
soooooooo, when she says Dev is alive, she's probably right (and we know she is!)
and when she heard that mysterious person singing, and said 'that's Dev's voice'...again I think she will b right...cause even if the guy doesn't look like Dev, I think it might b him in disguise! 😃
