amy pulled the doctor with her "come on!" she said " I haven't bought any clothes in ages. the doctor stared at the control desk for a moment before sighing and walking with amy. "the TARDIS needs to rest anyway. no harm in a bit of shopping."
together they walked through cardiff, having rory left behind in the tardis, asleep. " which store then?" the doctor asked. " that one" amy said and pointed. before they could enter a young woman, she might not even have been 18, walked up to them. " sorry to bother you," she said shyly "but i couldn't help it notice you're not wearing a black ribbon today."
"why would we?" amy asked
the woman turned to the doctor. " you have that look we all have."
the doctor looked confused. " what look?" he asked "this one?" he pulled a funny face
"no," she said patiently "a look of pain in your eyes. you've been through a lot. we all have." she showed them the black ribbon. "why don't you join us later today?" she said and gave them both a flyer with a black ribbon attached. without a further word she left.

"national anti depression day" the doctor read "I'm not depressed!"
"but you do have that same look as she had." amy said "strange, I've never noticed it until now."
slowly but confidently the doctor tied the ribbon around his wrist and after a moment of doubt amy did too. " what is this about then?"
"my family" the doctor answered in an almost broken voice.
"but you're the last of your kind. you said so yourself."
"you saw the look in her eyes, didn't you. the same as in mine. it means we've suffered." with those words the doctor turned and started to walk back to the tardis without another word. this subject was over.
suddenly he turned again to amy "do you know that rory has that look too, he carries it like a soldier."
they walked silently and suddenly, without amy having realized it, they had arrived at the address on the flyer. "why are we here?" amy asked
"the universe isn't all wonder and excitement." the doctor explained "sometimes it's pain and war. i don't want you to forget that." they went in. inside there were about fifty people sitting in chairs. most of them on their phone, tablet or laptop, but some others chatting. in one corner there were half a dozen soldiers chatting softly with each other. the more careful amy looked, the more of that same expression she saw in their eyes.
"but most of them are kids!" amy said upset "they can't have been through that much pain."
"these are the outcasts of the human kind." the doctor explained "society has turned against them. most of these girls cut them self to feel better. some of those boys starf themselves because they are bullied. you remember Van Gogh, don't you?"
"how could i ever forget?" she answered surprised by the sudden change of subject.
"he was one of them too. these people are haunted by depression, PTSD, autism and so much more. they don't choose this amy."
amy was quiet, overwhelmed by the pain and sadness in the room and by the memory of vincent.
"we... we have to do something" she finally said.
"these are not our wars to fight" the doctor answered, sad "lets go."
