This is important to put a spanner in Nani-Tapu plans; if Veercha do not consummate their marriage soon Nani-Tapu plan wins because everyone INCLUDING Iccha will put pressure on Veer to take Tapu back for the sake of the 'child'.
If the marriage is consummated it ties Iccha much more closely to Veer and also gives the argument that Veercha cannot divorce because of the possibility of Iccha being pregnant. Also Iccha will fianlly get a back bone with regards to always giving in to Tapu because it's HER child at sake.
Can't wait for it to happen about time we got some proper romance from them!
