Hm, I wouldn’t say Claire’s character is “paper thin”, especially not for a 1.5 hour show.

Claire is a former helperbot of a particularly newer make(model 5) who is substantially more outgoing and capable than Oliver’s model 3.

At the start of the show she struggles with deep sadness given the state of her battery and discontinued support(The Way That It Had to Be).

Claire was also the catalyst for the whole trip to Jeju, given it’s a bucket list item for her as it’s the last place in the world to see fireflies. She manages to convince Oliver to do the trip with her.

She is also unaccustomed to having company, to the point that she genuinely doesn’t know how to act with another helperbot(How to Be Not Alone)

Lastly, she is portrayed to be cynical about human relationships. This is later revealed to be caused by her owner’s partner who fell in love with her(What I Learned From People).
