There is no denying that they are soulmates. If we can't have the typical romantic scenes, can we please at least have their friendship intact? Their relationship is eternal, they haven't fallen out of love (I don't think they ever will either). They can't just stop showing AR scenes so even if they have their scenes with K and S, AR should remain best friends, friends whom know when the other needs a shoulder to cry on or needs advice.
I know Armaan had once said that they can't just be friends but their relationship is such that they will never be just friends anyway. They might not be lovers in the conventional way but they're bonded for life and beyond life. The least the creatives can do is show them being there for each other no matter what, no matter who they are with.
And who knows where this could lead to...
