Two points I would like to mention:
1.Archu has tolerated all abuse from savita,shravani for no reason at all.Now,today when she encouraged Vandu to slap her,atleast she had a reason to take the slap...had she stood up against it,only Vandu would have suffered more...Archu has witnessed clearly how cunningly Rasika n Ajit manipulate situations,so she just thought about Vandu...atleast Rasika will refrain from physically torturing Vandu.I actually dont see how Archu could have fought against it when Vandu herself has chosen to be the sacrificial lamb
2.The only way,the things look now,if Archu has to fight for Vandu ,it has to be as cleverly as rasika and beating her in her own game rather than going openly against her....she openly went against Rasika and saw what happened....I just hope she'll be smarter this time around in fighting against Rasika.
As far as the slap is concerned,Rasika would have tortured Vandu,hadnt it been Archu....so it was between Archu n Vandu...Archu took it trying to spare Vandu...and I dont think Rasika is a lady who needs encouragement from Archu(in the least) to continue with her slapping strategy....Archu had two choices...first,get slapped and encourage Rasika...second stand up and yet again encourage Rasika to torture Vandu.....She chose the first option which seems better for the time being.
Whatever they are showing in PR is no where real...so I dont want to get to the reality factor of the situations....its difficult to believe this story takes place in Mumbai...joke of the millenium
