Cero Sullivan

🧩 10 Hobbies

1. GeoGuessr & map games
Road markings, bollards, landscapes, languages, utility poles. He’s learning to read geography through clues.

2. LEGO city building
His cities have transit systems, parks, robots, ridiculous skyscrapers and surprisingly detailed municipal planning.

3. Beginner robotics
Sensors and motors fascinate him because machines can react to their environment.

4. Coding games
He enjoys coding most when the result immediately does something.

5. Drawing inventions
Some are plausible. Some involve jet propulsion where jet propulsion absolutely should not be involved.

6. Collecting world greetings
A hobby that quietly teaches geography and culture at the same time.

7. Science exploration
Volcanoes are currently near the top, with weather, geology, animals and space orbiting nearby.

8. Museum expeditions with Hazel
His museum strategy differs from hers considerably. Hazel reads every panel. Cero finds the interactive exhibit.

Together, they’re formidable.

9. International snack archaeology
Candy wrappers and unusual packaging sometimes survive because he likes their languages and designs.

The candy itself has a considerably shorter archival lifespan.

10. Photography & visual travel journals
Signs, unusual buildings, trains, maps, strange street furniture and anything he wants to remember later.

🎧 10 Artists

Cero’s musical DNA should remain flexible enough to evolve as he grows.

1. Imagine Dragons
2. AJR
3. Twenty One Pilots
4. Coldplay
5. OneRepublic
6. Owl City
7. Jon Batiste
8. Lindsey Stirling
9. Stromae
10. Yo-Yo Ma

This gives him pop energy, unusual production, cinematic scale, international curiosity and instrumental music for concentration.

His Cero’s World soundtrack can gradually change as his own musical identity emerges.

📺 10 TV Shows

1. Wild Kratts
2. Carmen Sandiego
3. The Magic School Bus Rides Again
4. Odd Squad
5. Brainchild
6. Secrets of the Zoo
7. LEGO Masters
8. Doctor Who
9. Avatar: The Last Airbender
10. Pokémon

His wildcard: Doctor Who

This is where Hazel and Cero’s interests collide beautifully.

Hazel:

“Imagine actually witnessing history.”

Cero:

“Yeah, but I’d go to the future first.”

Naturally.

⚽ 10 Sports Teams & Athletes

Cero’s interest is driven by spectacle, extraordinary skill, geography and people doing things that appear physically impossible.

1. Philadelphia Phillies
2. Philadelphia Eagles
3. Philadelphia Union
4. Philadelphia 76ers
5. Pittsburgh Pirates, partly through Hazel’s family connection
6. Lionel Messi
7. Simone Biles
8. Stephen Curry
9. Shohei Ohtani
10. Kylian Mbappé

GeoGuessr occasionally infects his sports viewing.

A stadium appears on television and Cero wants to know where it is before he wants to know the score.

🎬 10 Movies

1. WALL-E

Robots + space + Earth + enormous questions.

Very Cero.

2. Big Hero 6

Technology becomes interesting because people decide what to do with it.

3. The LEGO Movie

A civilization made of building blocks was never going to miss this list.

4. Spider-Man: Into the Spider-Verse

5. Spider-Man: Across the Spider-Verse

The multiverse is basically geography with the difficulty slider broken.

6. The Mitchells vs. the Machines

Technology, family chaos and robots behaving badly.

7. How to Train Your Dragon

Learning about something changes the relationship with it.

8. Paddington 2

Kindness as an actual force in the world.

9. The Iron Giant

A machine doesn’t have to become what somebody designed it to be.

That idea stays with Cero.

10. Akeelah and the Bee

Curiosity, language, learning and community.

🧳 10 Destinations Already Visited With Hazel

These intentionally match Hazel’s established travels because these were mother-and-son journeys.

🇺🇸 1. Washington, D.C.

Cero remembers the museums, aircraft and enormous exhibits.

Hazel remembers considerably more explanatory text.

🇺🇸 2. Boston

The Freedom Trail became an elaborate real-world scavenger hunt.

🇺🇸 3. Colonial Williamsburg

Cero became fascinated by how ordinary things worked before electricity.

🇺🇸 4. Charleston

An important trip where Hazel began introducing him, age-appropriately, to the difference between remembering history and romanticizing it.

🇨🇦 5. Montréal

A breakthrough destination for his fascination with language.

Two languages appearing naturally around him made multilingualism tangible.

🇨🇦 6. Québec City

Walls, fortifications, steep streets and French signs. Cero’s visual brain had a banquet.

🇬🇧 7. London

Transport map heaven.

Hazel had historical priorities.

Cero discovered the Underground diagram.

Everybody won.

🇬🇧 8. York

Vikings.

There was never any chance York would fail.

🏴 9. Edinburgh

Castle + volcanic geology + winding streets + maps.

Cero approved.

🇫🇷 10. Paris

His Paris memories aren’t Hazel’s Paris memories.

His include the Eiffel Tower’s engineering, Métro maps, pastries and trying out French words he’d practiced beforehand.

That distinction matters.

They travel together without experiencing the same journey.
