She'll go to the party instead

Iris didn't know what she was going to do exactly, but she knew she wanted to help him.

"I'm invited to the party.", she said. "I can go there and steal them for you."

She saw his mouth open wide in disbelief. "What? How?" he stammered.

"Leave it to me.", she said assertively. "I'll need a way to get out of here, though. You got a ride?"

He scratched the back of his head, slightly embarrassed. "Well, I got my bike...", he pointed to a bicycle leaning against the wall at a distance.

She sighed. It wasn't the best, but it would have to do. "Get on your bike and wait here for me. Be ready."

He nodded, speechless. She saw him run to get his bike, and she went the other way towards the front gate.
