Who has the palm tree tattoo on the back of their arm?

Very random but I ran into one of the twins this evening but minded my business so I wasn’t able to tell which twin it was. I saw them again from behind as I left the shop we were in and saw a palm tree tattoo on the back of their arm.

I’m pretty certain it was Tegan but hopefully a bigger fan can confirm for me. Teenage me would have no problem telling them apart but it’s been a while.
