Cat Argument: New Tomcat vs. Old Tomcats

The new 2-year-old tomcat Hugo (brown-tabby/white) is too dominant for the old tomcats Buddy (black/white) and Tom (black). They have some arguments when they meet randomly. But these are only verbal arguments. Looks like Hugo starts to understand that it wouldn't be a good idea to start a fight with these experienced (not only in fighting) and dominant tomcats.
