Father and Son

I'm wondering if there is some way we can reinforce to the audience the father and son relationship between Antonio and Proteus. If maybe they both share some idiosyncrasy or gesture. The same would go for the Duke and Silvia. I just feel that there is still a disconnection there. Also, I am still working on how to work with the cane. I'm trying to figure out why Antonio would need to use it; age, ailment, or for authority. I want to use it.
