Davey has primarily trained at scrum-half with Wales and faces competition from Keira Bevan and Seren Lockwood.
And contrary to the stereotype of the position, the nines get along with no animosity.
“We all really enjoy each other’s company. We want each other to do well, so there’s never that hatred towards each other,” said Davey, who has previously started at fly-half for Loughborough.
“Whoever goes out there and does the job first is the best pick for the team and you just need to back that completely.”
Wales open their WXV campaign against South Africa at Cardiff Arms Park on Friday, 18 September (19:15 BST), and any potential involvement would mean the world to Davey.
“Playing international rugby is such a privilege and I want to make everyone proud – my family, but also the coaches that have been behind me for the last 15 years of my journey,” she said.
“It’s just that final step, like ‘I made it’. I’m really excited and hopefully it comes at some point.”
