-Hey Penny, table 3 wants to order.

Penny nodded as her friend passed trough, busy herself with her clients. The blonde picked her note pad and directed herself to the waiting client, who had their face covered by the menu.

-Hi! My name is Penny and I will be your waitress tonight, can I get you anything to drink?

As the menu was put in the table, Penny could see the person the face of her client. A blonde, young woman took her eyes off the menu to look at Penny.

-Well, just a Coke for now.

But Penny didn't move, she had her eyes wide opened as well as the mouth to the woman in front of her.

-Oh my god, you're Billie Piper- she said in a falsetto.

Billie smiled.

-Hello!

Penny kept staring at her, chocking in her own words:

- Oh my god, I simply love you. My boyfriend is a big fan of Doctor Who so I started to watch just to know what it was but I liked Rose so much that I became a big fan of the show!

-That's gr-

- No, seriously! I even dressed as you with that 50's dress and cute jeans coat for Comic-Con! I haven't watched all seasons yet but I liked Rose so much that I started to watch Secret Diary Of A Call Girl. and it's amazing- she said in a falsetto again.

Billie smiled in amusement and thanked. A few awkward seconds went by until Penny broke it.

-Sorry, but would it be too much if I asked to take a picture with you? I just really want my boyfriend to see this!

-No, it's okay!

Penny picked her phone from her pocket and took the picture, senting to Leonard with the caption "Your favorite blondes!"

Putting her phone back in her pocket, she turned her attention to Billie again.

-' Gonna bring your Coke in a minute!- and walked to the kitchen.

40 minutes later

Billie handed Penny the check as she stood up.

-Bye, enjoy Los Angeles!

Billie said goodbye and walked to the door. She stopped and came back to Penny.

-Sorry, just for curiosity- she said intrigued- You said that you haven't watched all seasons of Doctor Who yet. Which ones did you watch?

-Only one and part of two by now. Leonard, my boyfriend, he's being really slow to download the other episodes for me, it's like he is avoiding haha.

Billie sighed deeply. Penny's smile faded.

-What?

Billie looked at her in pity.

-Yeah, about the other seasons...

Penny opened Sheldon and Leonard's apartment's door and slammed behind her.

-Leonard!- she screammed.

Her boyfriend came running and smiling.

-Hey I got you picture! I can't believe you met Billie Piper, this is amazing!

His smiled suddenly faded and he realized her facial expression. Pouty lips and cold eyes stared at him in anger.

-Is there something wrong?- he asked gingerly.

Penny glanced at him another heavy look before she answers.

-Billie told me about Doomsday.

Leonard's face went dark as he stepped a few inches away from her.

-Oh, oh.

Penny got closer, hiding a smile as she saw his scaried face.

-You better run, smart boy.
