“We have just some funny phrases that no-one else really understands, but it really makes us laugh,” says Packer.
“She’s very good at making things quite light and I’m probably the opposite – I make it quite serious.”
There is plenty to be serious about when they face France in Bordeaux.
Given England’s home run at the 2025 Rugby World Cup, WXV’s sparse crowds and an expected record attendance at the 42,000-capacity Stade Atlantique, it is likely to be the most hostile environment the Red Roses have played in since that fateful defeat in Eden Park in 2022.
The streak of 37 straight wins England have put together since is in definite peril.
But, beyond her notes and focus points, there is something else, less easily defined, that bolsters Packer amid the stress.
“As a team we are all overly critical of ourselves, but there is a bond that’s really important to us,” she says.

Packer, her team and that togetherness will be tested.
