His trust on tia is boundless . Mentors moment bhi hua toh tia ki wajah se !!
Facepalm
But Tia also told almost everything except the reason.
When she met Shivaay, she thought shivika patched up because she saw their date pics on social media. So went on saying "I'm very happy u guys patched up n r together. I felt so bad on that day. Annika can only take such a drastic step. She did a sacrifice for u.She loved u so much and I think u understood by now how much she lives u. N I'm happy u took the reason for ur separation and accepted it". shivaay asks what reason she is talking about. Then Tia says u would have known the reason for separation. Shivaay denies Knowing anything abt it. He asks her abt it. Tia realised she blurted out by mistake n she escape from there citing phone call. Then Shivaay remembers how OmRu were taking Annika's side and asking Shivaay to forgive Annika, Pinky's fearing moment and then decides there is something which he didn't knew.
