Meanwhile, after weeks of flirting, Nate (Kyle Pryor) finally decides that he needs to have some fun following his turbulent marriage to Sophie Taylor.
After the doctor confides in Kat about his impending divorce from Sophie, he soon realises that it is time to have some fun.
Nate plucks up the courage to ask Kat out on a date, and while Kat is keen, she is also interested to know more about his history with Ricky Sharpe.
Pryor said: "From Nate's perspective, it hasn't been that long since Sophie left. He is just finalising the details of their divorce when Kat catches his eye.
"Kat comes across as quite cheeky and he appreciates that in her personality. He feels he can win her up a bit and maybe press her buttons."
