Iris tries very hard to receive hers in the spirit it's intended; she has to spend half an hour meditating to achieve it properly, but once that's done she's able to return fire in kind.

She uses leaf-thin titanium sheets to make half a dozen origami birds, and she reinforces their wings with silicon-bonded microfilaments to make them fly. They're not very good at it, but Iris feels that just makes them better.

Each bird is inscribed with a line of the following rhyme:

Violets are blue
Roses are pink
Sod Valentine's day
Just get me a drink

Then she loads each bird with glitter and lies in ambush to send them fluttering around Cold's head like drunken glitter-shitting butterflies.
