There was a pre-recorded item with Kylie Pentelow chatting to him whilst wandering around behind the scenes in the newsroom, gallery etc. They avoided referring to the fact it's in Bristol, keeping the item neutral enough to be shown on the "Plymouth" edition of the programme.
Similarly, when they demonstrated how chromakey works (Kylie called it "green screen". Ugh) they used a pan-regional map, with place names from the Isles of Scilly to Swindon labelled.
They mentioned that Charlie has been a meteorologist for 10 years. He doesn't look old enough, to me! Must've started before he'd even done his GCSEs!
