Overview:There's a dramatic start to the festive season in Holby following the gas explosion, which has left siblings Nic and Kelly fighting for their lives. The pair are rushed into hospital, where Jess keeps a vigil by Nic's bedside, while Kelly is rushed into theatre—and for Ric, who knows his colleague is a deranged murderess, this proves a real test of his professionalism, as he resists the temptation to just let her die. On a lighter note, Tom hosts the Holby Christmas bash, where an inebriated Tricia makes a complete spectacle of herself, while ladies' man Mubbs surprisingly opts to give the party a miss and do a spot of babysitting for Rosie instead.
