The tardis meets baker street #part 2

The doorbell rang. Sherlock raced downstairs and opened the door, standing in front of him was a tall looking young woman and a short man with glasses and a bald head. "Hi" the women said " I'm Bill and this is Nardole, we were sent he my a man named mike or something?" "Hello, yes I'm his brother. I was told there would be three people coming?" Sherlock replied. "Um yes the doctor is on his way, he uh got into an argument with the taxi driver." Nardole explained " here he is" said Bill. A very angry looking man came across the pavement cursing under his breath "ah hello" he said in a very  Scottish accent. "Come in" Sherlock said leading the way up the stairs.
"These are the people your brother sent?" John asked "yes, John very observant" Sherlock replied "so why exactly are you here?" So the doctor explained everything to Sherlock and John. "Urm..." John said clearly totally lost "Fascinating!" Sherlock exclaimed. "So are you on board?" Bill asked. "Yes of course, let's get to work" Sherlock replied.
They all got up and the doctor led them to the university where the TARDIS was. They all went inside, obviously Sherlock wrapping his head around it straight away and John, if possible, looking even more confused. "Yeah I was like that too at first, you kind of just get past it eventually" Bill said to him. "Ok sure?" He replied still bewildered but starting to simply accept what was going on. "So what is our plan?" Nardole asked disapprovingly looking at Sherlock and the doctor. "Well.." they said in sync looking at each other "improvise?" Sherlock suggested "oh yes" the doctor agreed. Nardole sighed loudly and Bill and John looked at each other worriedly. "So where can this thing take us?" Sherlock asked. "Well,she,can take us anywhere in space or time but you have to reason with her" the doctor explained. "So could we go to the home planet, or whatever, of this alien species?" John asked, seemingly quite proud of his idea. "No point" the doctor replied "It was destroyed by a huge war years ago. An escape vessel managed to get away and since then they've been repopulating on any planet they can get on, mimicking the dominant nspecies of said planet. It became my problem when they targeted earth." "So thought of what you're going to do first?" Bill asked. "Well lets go and find they're headquarters?" Sherlock suggested "Sure" agreed the doctor. They took a seat as the TARDIS began to whir into action.
