hey sontar-ha enjoy yourself on the foums
i am afraid i think jenny will die coz she'd be such a huge part of his life if she lived but there is no mention of her in the final

Good point, if she lived it would not work out because she would prob have to travel with him. This will totally ruin The Doctors life. I think she dies

good minds think alike

"Oh yes!"

I think she might die too.
(I thought Astrid was gonna die as soon as I saw the Doc's sad face in the VOTD trailer weeks before the episode aired.)
Or Jenny might refuse to travel with him, or the Doctor might not offer her a chance to travel with him.

From Digital Spy:

"The Adventures Of... Miss Martha Jones
Once again Martha gets her own subplot, having been kidnapped by the Hath and promptly written off as "collateral damage" by an unsympathetic - yet strangely perceptive - Jenny. Her peril is short-lived, however, as before too long she has befriended her captors and developed a master plan to find the Doctor, end the war and blah blah blah..."

sounds abit like astrid's situation huh
