Artist Dylan Schwarz and his assistant Elke arrive on K2 to set up a kids art project. Pippa is attracting the attention of Dr Kersley and obstetrician Dr Tatty Oxford, who in turn has a surprise of her own to spring on Den. Kim confesses that Dave has been offered a job in Iraq, Den ponders her own unexpected news and Pippa makes a discovery of a different kind in a corner at Chatters. Dylan's endeavours help solve one patient's diagnosis, but off the ward Den's announcement ends in a more brutal fashion with fisticuffs for Hilary. With Vag-At research a success, Pippa celebrates funding approval with a suitably open-mouthed Josh, who has a final surprise of his own to spring.
