Now it is Claudia Moloney-MacDonald's turn to fumble, dropping a long pass from Holly Aitchison, but it didn't go forward.
Ellie Kildunne gets the ball for the first time, and the decibel level goes up a notch or five! But Ireland cope well and kick deep into England's half.
England's Holly Aitchison gets the game under way, chipping the kick off deep to Eve Higgins, but the centre drops it and England get an attacking scrum straight away.
England wing Claudia Moloney-MacDonald and Ireland hooker Cliodhna Moloney-MacDonald are about to face off against each other for the first time since getting married last year.
The pair are Exeter Chiefs team-mates.
"I asked Claudia if they tell each other who is picked," England wing Jess Breach told BBC Sport.
"She said they only tell each other if they are both involved and not what the entire team is.
"She is excited, you are excited to play your mates and it is like that. It is nice that they don't come up against each other at club."

The atmosphere is building to a crescendo, and a graphic of the England team has just been seen hanging for most of the height from the top of a stand to the pitch.
The teams are in the tunnel, as are the mascots, and we are nearly ready.

England head coach John Mitchell speaking on BBC One: "New team, new start and new learning. The freshness of the new girls has brought an enormous amount of energy.
"I think our preparation has served us well. I think we are unfinished, we want to play a style of rugby that will bring us to the top again."
On Emily Scarratt in her new role as a coach: "She has been fantastic. The way she created an unstructured element to a structured element is amazing. She has insane knowledge of the game."

Bristol Bears prop Hannah Botterman is a doubt for the rest of the tournament with an ankle injury that has required a scan - the same ankle she had surgery on after the World Cup.
The 26-year-old - one of the Red Roses' top performers at the World Cup - has been one of the most improved players under Mitchell, developing her scrummaging and establishing herself as one of England's best ball carriers.
Prop Kelsey Clifford is given the nod to start and proved an able replacement in the World Cup quarter-final win over Scotland - which Botterman missed through injury - scoring twice to show her power in the carry.
Botterman's outgoing personality off the pitch will also be a loss for squad morale in team training.

England full-back Ellie Kildunne has admitted feeling "really alone" after experiencing an emotional dip following the Red Roses' Rugby World Cup win.
Four weeks on from winning England's first World Cup in 11 years, Kildunne returned to club action for Harlequins in front of 2,929 fans at Twickenham Stoop against Loughborough Lightning.
"You are playing in front of a sold-out crowd at Allianz, you have just won a World Cup, and the next minute you are back playing over the road in front of a sliver of the amount of people," the 26-year-old has told BBC Sport.
"There was that little bit of a dip in 'why I am doing this?' I always say it is for the happiness and inspiring people and every room I walk into."

With England's continued dominance comes a struggle to attract casual viewers looking for sporting jeopardy.
John Mitchell wants to keep evolving his side's game and create a dynasty by winning back-to-back World Cups, but knows the winning run will come to an end eventually.
"There is a Lions tour in 2027 so there are a lot of factors that will distract our girls along the way," he said. "If we do have a hiccup here and there that is also good to learn from."
Captain Jones believes the team's ability to play exciting rugby will enable them to keep selling tickets.
"Our role is to be the entertainers and make sure that we provide a product that people want to come back and watch," said Jones.
An improved standard of play - evident across the World Cup - could bring more entertaining and competitive games throughout the tournament.
More eyes will help keep the sport accelerating forward, but the product on the pitch needs to deliver for the increased numbers in the stands and watching at home.
