I actually think
a) Mohan was in love - he maybe didnt ever express this to "her" -
b) I wish this person had been Renu - and perhaps she never knew.
c) He tried speaking to his dad and it back fired on him - hence his advice to Anant - dont talk to "dad"
Maybe his talking to his dad BACKFIRED and he landed up with Rama
d) So his dad is even more wary with Anant - would explain his grouchiness
If so HOPE a) Mohan meets Renu - or whoever the lady was... and b) This gives RAMA some thing else to worry about!!!!!!
What do you think? Am I too way off base?
