"[5] Slaughter noted that "She's always there whereas other cast members such as Adam [Woodyatt] – who's been there as long as I have – wouldn't necessarily have a storyline that puts him in The Vic at all.

"[6] When Slaughter reads a script and finds a line for Tracey, no matter the length of it, she gets an "incredible buzz".

"[11] It was later revealed that bookmakers, William Hill had slashed the odds on Tracey being the killer, with 7/1 thinking she killed Archie.
