D K in the past were surely involved in causing rifts in marital life of loving couple M T and in provoking T to an extent that she showed her anger even on step mom thus making M lose his cool, eventually causing T to walk out of that house before her death.🤔D K also might be involved in creating a fake narrative of egoistic T committing suicide in her mad rage to defame M & his family with her death threat, which family believed all these years.
That safe locker cannot have any such 'valid proof' hidden from step mom all these years,😛 possibly it may have some document or jewel of T which if seen can hint M that T won't commit suicide?
Suddenly D K being worried of locker now which was earlier under control of Kadambari, looks so absurd just because an uneducated woman newly gets keys. 🤪
Still not sure that D K have direct role in T's murder, which might have happened outside this house.
