I wouldn't go so far as to say Kellie looks like Pat, but certainly there are times they have a similar look on their faces when they are intensely focused. And there are definitely times we can hear the same Middle Tennessee accent and phrasing. Kellie's quite a bit "softer" in her overall presence than Pat, if that makes sense, but at 44 years old, is still developing her presence.
That's way more than you asked for, as usual! lol
