Yeah the trilogy is amazing and I remember really liking the last story from the box set. Love older Sixie and Peri 🥹
I would love an actual ending to this arc, but Big Finish loves to leave arcs with companions open ended a lot or just introduce another version of Peri like in the last boxset

Omg same, it's been ages since the last!!! 😭

It's such an amazing arc too

I'm sure you'll find yours soon, the right person will come along eventually 😊
