A Bit Perplexed?? YEP! That's ME!

Hello my friends 😊 I am immensely confused. Is Viraf Patel going to replace Barun Sobti as ASR or is the character of ASR going to fade out and is Viraf Patel going to portray a new character (not ASR's character) in the show?? I have been wondering this for a long time and it doesn't seem very clear in the articles mentioning Viraf Patel's name...can one of you guys please help me??
