Who knows Om better?

1) Acc, to Om if in future a situation arises where he has to choose between His morals/ principles vs his family he would choose the truth- So he goes to Vanvas

2) Acc, to Ish if in future a situation arises where his ethics will take a back seat and he will become Selfish and Ruthless like his father- Shivaay going to Vanvaas and Om accepting to be heir.

I don't know but it will certainly be refreshing to see if Om turns Grey n for a certain time we see Shiv Kara rivalry of sort during Vanvaas track

So who do you predict will prove to know future Om better?

Him right now or Ishana?
