The prosecution and the defence have made their closing speeches at the trial of Melanie Smith for the murder of five members of a family in a flat fire in Prestatyn in October.
Prosecuting barrister Ian Murphy QC said Miss Smith had both the motive, and the opportunity, to start the fire.
He told the jury there had been another "flare up of anger" on the day before the fire and on the day itself, and she had taken her opportunity "with deadly intent."
Defending barrister Stephen Riordan QC said there was no direct evidence before the court to show how the fire started.
He said a number of prosecution witnesses had turned "gossip and tittle tattle into their own version of events", and that Miss Smith obviously loved children and young people.
She denies five counts of murder and one charge of making threats to cause harm by fire, and the trial continues.
