Hi @Anonymous User
According to the Sky TV Guide Planner, Blindspot Season 4 Episode 20 is scheduled for Monday the 3rd of June at 10pm on Sky Witness.
Based on the above information, i would expect this episode will be added to the NowTV catchup service within a couple of hours after this above live air date.
