The brothers get a bit closer in there attempt to save there sister and tbh I’m getting a bit invested in it

The Oil Well - 4.5/10

This is a very short part of the story, and doesn’t add a whole lot other than the fact Mary is still alive.

The Daleks have oil wells set up all over Venus and are using human slaves, Mary helps the Daleks be more efficient granting her passage to the other wells to employ the same plan.

Alls this part does in terms of character development is show that Mary wants to help, and shows that Jeff and Andy are ready to fight back against the Daleks by any means necessary.

So overall another decent part to a developing story but nothing magnificent it had to be said.
