No veera is not plotting anything going by Ratan's advice that by goodness even bad doing person will effected. So she is going by Gandhigiri so that Baldev will be shown the right path.
COMPLETELY AGREE WITH YOU. For a change she took Ratan's advice before reacting and Ratan was dead right, let them waste their time in plotting, but at the end of the day good always wins over evil. So, I don't think Veera is plotting, may be she is thinking in the same line as Ratan, let him waste his time, once he will realize, he will stop by himself.
NOTE : Her own ways of dealing with Baldev have never stopped him fro plotting evil, instead has boosted his ego, so she might be taking this new approach.
