Yes - he was talking to that lady a lot outside - she may be local - did they chat in the bar, too? She was playing with her hair a lot - flirting, likely, as Anthony is very attractive. I'm not suggesting any wrongdoing on anyone's part - purely an observation. The CCTV is so clear.
ETA - according to FB comments - the woman stated that they just 'exchanged pleasantries' outside the pub.
I'm still wondering about The Paddock and Baxters Field - not yet searched by the public according to the brilliant search map. Really close to the E&C pub, though AK may have been walking in the opposite direction...at this stage I don't feel confident about anything.
Also, Lewes Castle had a large wall fall down some weeks before - the rain may have affected some less well known structures in the area too.
Just thinking...and sending my very best wishes to Anthony's loved ones.
