I hate that he's using the eviction as an excuse to try and wipe away the fake address
Russ knows he doesn't have a leg to stand on and that the moment the Judge wakes up and rules on anything he's toast for giving the court and defense an address he admits is fake in his exhibit (which showed a bill for East Twain Street) and in emailing Hardin "As for the address, I'd have to know what you plan on serving me with" and his own hooker PAC website using his real address.
Russ is using this change of address to say "You know what, that address doesn't even matter either way, just send stuff to this address for now" as if that undoes repeatedly lying to the court and defendant.
And it's a PO box, so his eviction shouldn't even affect that address, but he used the excuse anyway.
