did she even talk to them? š²@rushiii yep she knew of arjunas existence ... I mean... drupada .. So obviously!
But she didnt knew who they were .. Or that is what is said in the ganguli trans.
Some version say that she knew cause ... Krishna <_<
But generaly, she saw these five brahman bros with their mother and instead of talking about dharm-shastr-bhakti, they talked about this weapon and that mantra, this shastra and their use and that astra and how to stop it.
So she started suspecting ...
