With his phone in hand and a nurse on hand to charge it up as necessary, Tony's main problem was getting the coppers away from him so that he could help himself with his own investigations.
He got proactive.
"Are you charging me with something?" he asked DI Thompson when he 'popped in for a little chat'. When the detective answered in the negative, Tony said quietly "Then why don't you fuck off and take your monkeys with you?"
"We're here for your protection!"
"I need fixing, not protection!"
Thompson promptly left, but left a uniformed man outside Tony's room.
