Chell was a child in an adult body, with a dangerous toy (her smaller portal gun.) Now that she’s been living normally for a while, she’s gotten more adventurous and especially more expressive.

Like now, as you walked around your apartment she continuously messed with you with that damned portal gun.

PORTAL. She slaps you. ANOTHER PORTAL. She yanks your hair. ANOTHER DAMNED PORTAL. She pokes your nose.

“Ahah…ahaaaahah…”

Talking still eluded her, beyond basic words like “food.”
