Actually I can think of some dark humor if/when they go aboard the Defiant. Archer's head mounted on the wall. I forget if T'Pol and Phlox got killed but maybe one of them is still on the ship. We have no idea on the lifespan of a Denoboliun. All the dead bodies of the original crew STILL hasn't been taken care off. Now it's just a bunch of bones and old style Starfleet outfits laying around. They use 60's era looking sets yet everyone is amazed at how advanced it looks.

t'pol got killed on the nx-class uss avenger -> no petrified vulcan ear bones for you, i'm afraid
