The pool erupted with a tremendous splash. The crowd drew a sharp intake of breath. A second bear had leapt into the water. He—she?—paddled through the blue toward Amy. So now there were two, bumping the glass just inches from her face, their bodies big as automobiles, their white fur rippling in the underwater currents.

“Will you look at that,” someone said. It was the woman Lacey had seen at the kiosk. She was standing beside them, holding her infant up to the glass by the armpits, like a doll. The woman, whose long hair was stretched away from her face by a tight ponytail, was wearing shorts and a T-shirt and flip-flops. Lacey could discern, through the folds of her shirt, the still-loose belly of her pregnancy. The husband was behind them, guarding the empty stroller and holding the camera.

“I think they like you,” the woman said to Amy. “Look, sweetie,” she sang, and jiggled the infant, making her arms flap like a bird’s. “See the bears. See the bears, sweetie. Honey, take the picture. Take … the … picture.”

“I can’t,” said the man. “You’re not looking the right way. Turn her around.”

The woman sighed irritably. “Come on, just take it while she’s smiling, is that so hard?”

Lacey was watching this when it happened: a second splash, and then, before she could turn her head, a third. She felt the glass bulge beside her. A ridge of water crested the lip and began to fall, everyone aware of what was happening but powerless to act.

“Look out!”

The icy water hit Lacey like a slap, filling her nose and mouth and eyes with the taste of salt, hurling her back from the glass. A chorus of screams erupted all around. She heard the baby’s cry, and then the mother yelling, Get away, get away! Bodies banged against her; Lacey realized she’d closed her eyes, against the stinging salt. She tumbled backward, her feet catching and tripping, and fell onto a pile of people. She waited for the sound of the glass breaking, the slam of the tank’s unleashed water.

“Amy!”

She opened her eyes to find a man looking at her, his face inches from her own. It was the man with the camera. Around her the crowd had fallen silent. The glass had held after all.

“Sorry,” the man said. “Are you all right, Sister? I must have tripped.”

“Goddamnit!” The woman was standing over them, her clothing and hair soaked through. The baby was screaming against her shoulder. Her face was furious. “What did your kid do?”

Lacey realized she was talking to her.

“I’m sorry—” she began. “I don’t—”

“Look at her!”

The crowds had backed away from the tank, all eyes locked on the little girl with the backpack who was kneeling before it, her hands on the glass, and the four bear faces crowded against it.
