The first round, Charlie won. The second round is harder to judge since it went beyond what we could see or hear. I think Finn nipped him about midway on his back. Noting much but maybe a blow to pride? I also feel that in spite of the tussles, Charlie wants Finn out. They may push each other’s buttons and Finn still needs to be isolated if you leave but I truly think that Charlie looks forward to having Finn around. Chirping is something usually done to kittens. Some of what Charlie does is similar to being a parent. He is calling Finn, teaching him and even disciplining. Finn is more like the rebellious teenager. Maybe Charlie just wants to get Finn properly in line. Lol I see this when I bring younger cats into the mix. Wanda Heart is younger than Finn but the girls she lives with still get a little fed up with her antics at times and give her a swat or a hiss. Alley and Liberty will quickly put her in her place. Callie has more patience. Tortuga is more likely to act as playmate. Wanda Heart seems oblivious to discipline most of the time but once in awhile she runs to me to tattle on one of the others. It’s very much like raising a family.
