They only got about halfway through the film.
Hamish was resting his head on John's chest, his hand dipped in the salty popcorn box when suddenly a loud series if banging sounds came from their door. Out of instinct and shock, they both slept up off their seats and ran to the door. Hamish got their first, crying in shock from opening the door. Scarlett stood outside, crying her eyes out, and covered in mud. She took one step in and hugged Hamish, he sobs becoming louder.
"Scarlett?" Hamish said, not knowing what to say. "Whats happened?"
She cried and hugged him more tightly, "Hamish," she said between sobs, "I don't know what to do."
John put his hand on her back, "Scarlett what's happened? Come on and sit down."
"I'm sorry!" She said as she was lead to the sofa, "I'm so so so sorry." She plunked onto the sofa, "I'm..."
"Scarlett, whatever has happened don't worry, okay?" John and Hamish sat down next to her.
"Can you tell us what happened?" Asked John.
She breathed for a few minutes, trying to calm herself down. She was was wearing, Hamish noticed, a brand new coat that she had got for her birthday. Hamish had got her some boots to go with it. She was wearing one of them, and her school shoe on the other. She had left in a hurry then.
"I.. I.." Scarlett started, "my, mother." She breathed, "I was phoning her and-" she was unable to speak for a moment and seemed to get angry with herself, "Urh! Sorry I-"
"Do you want to wait a moment?" Asked John.
"NO!" Scarlett half screamed, "sorry, sorry. Sorry John."
"It's okay."
"Right. I was phoning my mum and suddenly she was stopped and the phone stopped and I heard a scream and I don't know what to do!"
John took a breath and then closed his eyes, "okay. We can work with that. Do you know where she was?"
Scarlett nodded, "yes, Charing Cross Station. She works in the library near there."
"The one with the cafe?"
"Yes."
They sat there in silence for a few seconds before Scarlett said quietly, "can you help?"
"Shouldn't be too hard," John smiled at her, "do you want to stay here tonight?"
She stared at the fire for a while, "I don't want to bother you."
John smiled, "no it will be fine. Look, I'm sure I can get the sofa bed out and then you can sleep in my room and I can sleep on that."
"I can sleep on the sofa if you like." Said Scarlett.
"No, guests should get the actual bed. Social protocols."
Scarlett smiled, "thanks, John."
John smiled, "hungry?"
"Starving."
John walked over to the kitchen and Hamish started texting on his phone, "Scarlett?"
"Call me Lottie, Hamish, please."
Hamish froze for a moment, "okay... Lottie, what does your mum look like? Or what was she wearing?"
"Why?"
"Mycroft has access to security cameras."
"Who? No, don't worry. She has brown hair and a red coat."
Hamish nodded and told Mycroft, "thanks Lottie."
