Shall I assume you mean season 8 episode 16 'Decisions, Decisions'? This aired in the US on the 17th March, however as you are probably aware that here in the UK we tend to be a few weeks/months behind.
Fingers crossed the UK gets it in April, but as its a show I don't follow I cannot truly comment.
