I'm personally not in favour of wildcard rounds UNLESS they were planned from the very beginning. Like in JDJ2, I thought it was kinda crazy to have an impromptu wildcard round announced because of a particular elimination.
As for this Jalwa Number 10, yeah, it does seem to be a little bit arkward at such a late stage of the show - along with the fact that the team will have the support of 2 fan followings rather than one π³
However, I'm sure that it was meant for the sole purpose of spicing up the show. There is also quite a strong possibility that the new team won't be accepted with open arms by the audience... either way, the two celebs are very good dancers, and so the other teams will definitely be inspired to do better - in particular Rakhi.
God bless.
