Theory of 'More loyal than the king'

After looking at today's SBS segments, I feel that why is Anika behaving the way she is.

Shivaay has not said anything, bus isiko padi hai.

And now this patni and sauten drama??? I mean suddenly??? the guy has served you the divorce papers, remember???

I mean Shivaay has not denied that the kid is his, then why is Anika so vehemently denying the fact . She is suffering from the 'more loyal than the king' syndrome. Pata chal kal kpo Shivaay says yes mera baccha hai and corner's Anika with another 'Mafee Mango' scene.
