I have been wanting to reply to this post since yesterday. I love your observation and as I was watching today's episode I see exactly what you're saying. Asad is going through some significant changes although at an unconscious level. The change is affecting him emotionally, psychologically and now physically. Not sure if you noticed that when Zoya moved the tissue box today he moved it back as if he is trying to fight these changes and when she moved it back he doesn't notice. It was interesting that the CVs are showing this change in this subtle manner.
