Yeah if she was in London for any other reason than Tom she could be more open about it - or at least not SO undercover (chartering planes, etc.). & the coincidences of Emmys & other LA same timed LA visits last fall, Thor wrapping/trip to UK, post-Sudan timing of going undercover, & GGs are too many directly connected to Tom to ignore. Is is possible to otherwise explain them? Maybe. But is it plausible & likely? NO - not unless that explanation is Tom! Plus her missing Abi's dress/LBT concert.
