Also Elena telling Dev that he always fulfils golu's wishes that's why he is doing bad in studies so somewhere she holds Dev responsible for it.
Maybe this track is to again show how Dev who had failed as a son, brother & husband also fails as a parent. Also how he has still not learnt to balance relationships and Sonakshi's talk to him on the need of balance for a good recipe just adds to that.
I might be reading too much into the situation but it's just my POV. no offence.
