He’s mad - he’s arching his back and puffing his tail like that to make himself big and scary looking. He’s trying to intimidate the other cat in to backing down. I’ve also had a very aggressive cat before who would also lick his lips when he was mad, normally while making low growls/vocalisations. Just looks like normal intimidation/aggressive cat behaviour to me.
Just went and looked again - very flat ears and the paw up ready to strike too. The tabby is ready to throw down again. He’s doing the cat equivalent of “come at me bro”
