Are they really deviating enough to actually change the sequence of events? It would actually be an interesting change.
If ninad had heart attack now and saw Ashwini take care of him, it may make him introspect on his behavior with Ashwini in contrast and feel guilty.
In KD this track was much later. And it was more about Sais bond with ninad becoming strong. He only wanted Sai to take care of him....and says that publicly.
