I assume a good one, as he was kept down a year pretty early on (age seven, I think, according to Backwards the book). Also in Backwards (the book) the younger Ace Rimmer seemed to get on more with his mother and brothers at the least. (Last chapter: "The Difference - 2".) Could anyone actually get on with Rimmer's "father"? From what we've heard of him he seems pretty nasty. I think I'd prefer the gardener.
