Earlier this week, Stenson's long-standing character Steph Roach was killed in the Il Gnosh fire, which was lit deliberately by an unknown perpetrator.
Writing on Twitter yesterday, Whittle praised his former co-star and ex-girlfriend after watching the episode online. He also commended Ashley Taylor Dawson (Darren Osborne), Helen Pearson (Frankie Osborne), Anthony Quinlan (Gilly Roach), Glen Wallace (Malachy Fisher), Jennifer Metcalfe (Mercedes Fisher) and Nick Pickard (Tony Hutchinson) for their performances in the climactic edition of the teen soap.
In a tweet to Dawson, the actor commented: "@ashoztd Mate heard you were fantastic this week on the show with Stens, tryin to find it but no 4 On Demand! Someone stick it on youtube!! (sic)"
Later, he added: "OK, just caught up with oaks on youtube. Carley Stenson, @ashoztd, Hels Bels and Quinny, you just had me blubbin my heart out. Glen, Jen, Nick awesome too."
Whittle - who is currently on holiday in the US - bowed out from his role as Calvin Valentine on Hollyoaks earlier this year. Get the Inside Soap magazine on your iPhone or iPad
