Siblings - Season 1 Episode 5

High-flyer Gavin from the flat below asks Dan to feed his tropical fish whilst he is away. Miraculously the fish survive but, having the key to the flat, Dan passes himself off as Gavin, throwing a party at the flat. Here he has sex with Gavin's ex-girlfriend before the real Gavin returns and throws him out. Hannah falls for busker and ex-rock star Bryn, now a born again Christian who has eschewed sex before marriage. Desperate to get into his pants Hannah reunites his old group but still misses out as now he only wants sex with groupies.
