I tried to graphic again.
‘The TARDIS brought me home’
That line.. it’s on a par with 'I won’t forget you, you know’ for me, because it signifies so much.
When Three was first exiled onto Earth, he was so bitter about, so irritated with being stuck in one place with a load of thick-headed soldiers. So what this line is saying, is that at the very end of Three’s life, he is accepting UNIT as his home, because he has realised how much he has grown to love the Brig and Liz and Jo and Sarah and all the others.
I just… I can’t… ;A;
