[Mrs. Don-o]

I noticed that myself. I'm wondering if it's a variation on "Ti" as in "Ti-Grace Atkinson", (pronounced TEE-Grace) which is a legitimate shortening of "petite", amongst the Cajun and Haitian French-speakers.

"Little Erika," like "Little Grace".

Or maybe not.

Maybe her parents named her Erika, and she added “Te-” to be unique-y.
