All I had to see was that Tucker was in CANBERRA after knowing that is where JA flew into. It's called DISCERNMENT kneegrow.
Now I don't know for 100% certain but it's not that hard to intuit that Tucker just habbening to be in Canberra as JA arrives is no fucking coinkydink. I assume he's in contact with Stella which is how Tucker would know.
And no, I did not IP hop. Twas at werk and it was miller time so I had to reconnect once I drove 30 minutes home.
