Yes Bob was constantly monitoring radio traffic throughout BG.
Given this there is absolutely no reason Bob couldn’t act like a mobile phone to Harry, it would be hilarious if Harry lifted Bob to his ear to make or receive a call, the new Storm Front limited edition cover of Harry with Bob in hand brings this to mind.
And of course Cockney rhyming slang for telephone being “dog and bone”, often shortened to just “bone” would be wholly appropriate.
“The Looney Tunes themes went off in my bag, I reached in and removed Bob, holding him to my ear.
“Do you mind if I answer the bone?” I said to Mac.
“I have been expecting an urgent call”
Harry should be able to get a pristine phone and number, have it rung by a third party next to Bob and have Bob “Clone” it so that calls are received and sent by Bob, with normal billing to the Castle. He could do the same with Maggie and Bonea, so he could always keep in touch with his daughters, he was worried what was happening throughout BG to Maggie.
The only problem would be if Bob discovers phone sex.
Toot on the other hand would make an most excellent Drone.
