Doctor Who crossover
I'm looking for a crossover fic with DW. Rodney was at some scientific conference and when things go sideways, the only competent person around is Donna Noble. She helps Rodney with the crisis, almost dying in the process when the Doctor's blocks on her mind crumble. Rodney brings her to Atlantis to save her life, she ends up staying as an assistant to Woolsey, and she and Rodney get together in the end.
