Phone at Anika...what!

I'm confused
So just because shivaay's phone is at Anika's house, that does not prove that he was with her
People lose and misplace phones all the time
So Anika having his phone doesn't prove he was there...

Plus he answered the phone at home
If om is asked "was shivaay home" he will say yes
Which again doesn't explain shivaay being at Anika

If they use the logic of phone with someone implies where that person is
It doesn't add up
But let's see...

Only option is Anika lies to prove him innocent
Please no woman don't ruin your morals for mr sso
