Hey are there things lost or trapped inside the TARDIS?

Castrovalva. Though the Doctor is not at his best, and explaining it in terms Tegan can understand ("Zap!")

While I do think there were things that were lost in the TARDIS, I also think the TARDIS "cleaned house" whenever it exploded/crashed and then disappears for a time to "regenerate" itself. I believe the TARDIS also knows what to keep for the Doctor and what to delete, IMO...

In Death to the Daleks Sarah knocked an Exxilon unconscious in the console room. It never gets mentioned again.

Since the Zero Room was jettisoned in Castrovalva, did another one get constructed?

Certainly in the audio/comic/novel media. We've not had any mention of it on-screen.

Rooms can be replaced - the swimming pool was deleted in The Doctor's Wife but Clara found it in Journey to the Center of the TARDIS.

Fun fact: I just found out Karen Gillan couldn't swim (maybe she still can't?) as there was going to be a scene featuring the pool in The Doctor's Wife but it had to be cut for that reason.

Pond can't swim... giggle
