I am guilty of over-thinking LOD.
There’s been a lot of talk about BBC negotiations for further series and I think series 5 may have originally been written to be more final.
If Ted has been exonerated, but forced to leave the Police, the scene where he appears to give the £50k to Mrs Corbett would have been more powerful. Perhaps the note Kate read at the end would have said “we’re off” and Steve would have been hitting the pills a bit harder.
Instead, later knowing there would be a S6, extra bits were added: Dot’s third (and unforgivable) dying declaration, Kate’s (Touch of Cloth-esque) Dot Dot Dot Dot, and Ted being re-instated.
I need to stop thinking about this TV show now, but I can’t, I’m enticed by the glamour!
