This isn't her memory. That becomes clear immediately — did the Winter Mourning not work...? — but there's no time to question all of that too much, because Rose is being pulled right through it. She's standing in a crowd of people as it rains, watching the scene unfold before her. She's part of the people who circle in on the.... two creatures that look like people except not, with their bright colours, gills, scales, tails....

(She's seen scales like that before, she realises—)

Though she's trapped in someone else's body, Rose feels a horror blossoming as some of the people lift their weapons, as the energy of the crowd ripples, some of it fearful, others... angry.

And she recognises the voice of one of the creatures; she doesn't need to be told who that is. It's Luca. Rose watches, helpless as the older-looking boy, Ercole, speaks. '—but we're afraid of you. Everyone is horrified and disgusted by you, because you are monsters.'

She hears the word whispered through the crowd around her, monster, monster and sometimes, more specifically... sea monster. Like it's a word they all know, some taboo, frightening thing.

That's when the memory ends, and she's left trembling in the living room of her home, where she's holding her Winter Mourning.

Rose blinks, open-mouthed and stunned for only a few short moments, before she's scrabbling immediately to her feet, grabbing her coat. She knows where Luca lives; in her searches for her daughter, she was told about a few houses where young folks have congregated together, and she means to go find him now.
