I'm looking for the word for the sort of bitterness and exasperation as excellently exhibited by Eric Birling of J. B. Priestley's An Inspector Calls:
When Eric works out that Sheila has informed their mother of his alcoholism behind his back:
Eric: You told her! Why, you little sneak.
When Eric finds out that his mother has inadvertently instructed the Inspector that he should be punished severely:
Eric: You haven’t made it any easier for me, have you, mother?
The word "sardonic" comes to mind, but this doesn't quite describe it; he's not making a wry comment to mock somebody or as an attempt at humour. He's frustrated to angry in both examples.
What word can I use to describe this? (Bonus points if it has a noun, adjective and adverb form.)
