First of all...

I went inside of Defiants tardis flew some distance away

And built a Tardis. Then linked it to my Own exterior

Then Defiant starts claiming its his Tardis even though its all mine with a little help from friends.

Then he starts trying to grief it.

When I said I was going to move it to some unknown co-ords in the tardis dimension and remove the original He started saying NONONO

 I'll deal with it now.
