What are the chances of Congress & where does INDI alliance stand?

After the massive downfall in Bihar Assembly polls-2025 Congress now looks forward to better performance in West Bengal, Assam, Tamil Nadu and Kerala. In Tamil Nadu, where they have a secondary role and are banking on DMK and Mamata didi in WB since she has a strong hold in the state.  But would didi be keen on shaking hands with Congress after its mighty Bihar defeat? So, that leaves Congress with Kerala (where the Left has a strong hold) and Assam. Under these circumstances the big question is if this is the case of Congress what is going to happen to  INDIA block.
