Howling:Is the Tardis sick/injured?

In The Curse of the Black Spot, the "siren" takes injured and sick people into the sick bay. We know why she took the pirates, the Doctor and his companion. But apparently she also transported the Tardis. Why did she do this? Is the Tardis "sick" or "injured"? 184.160.209.204 16:55, May 9, 2011 (UTC)
