from a track point of view... Ganga's entry to TN is non of her business so CVs found a way to keep her away (for now) else they run the risk of making her come across as interferring, or uncaring towards her own relationship with her hubby because we all know that she's not one to stand quietly by and not involve herself when she sees this innocent girl being fed to the wolves
... also, I want to believe that the days of P being the moral compass for K are numbered as he's going to start making these decisions himself without her having to point out / explain what is wrong or right.
From a relationship point of view... its can't happen so soon else it will look as if there's no lessons learned.
yes it was due to manipulations, but lots of hurtfull stuff was said by Krishna. He needs to come to terms with what his mother did to him, what his mother did to his wife, and most importantly, what he did to the love of his life. Krishna has to remember than nothing good comes too easily.
Besides who would want to go back to that jungle right away? Even if her mate resides there, he's not the alpha lion and can't provide 24/7 security.
