actually to correct you a tad bit, it's series 2 episode 13 that is Doomsday, and she does appear again in series 4! the episodes are "Turn Left" "Stolen Earth" and "Journey's End" and she also appeared in Tennant's last episode "End of Time Part 2". She was my favorite compainion so i need to know these things!

She was a fantastic compainion, I was so sad when I watched that episode but I guess she is happy on the


Rose was a fantastic compainion- Doomsday was such a sad episode, it made me cry

hope she comes back

After the end of time part two. I really don't know when or if she will come back. I hope she comes back.
