Sorry, but "yeuch".
The thought of this pair getting it on, steamily or otherwise, leaves me cold. Don't get me wrong - I love Ciaran. He deserves a decent storyline AND a decent love interest. Michelle's okay but just the wrong person for Ciaran, in my opinion. No. It should be ME, ME, ME!!
I think I'll do a Mary and buy a camper van. I'll get her recipe for hot chocolate with "just a hint of brandy" and set myself up outside Granada studios. When Ciaran/Keith walks past, I'll open the camper door, stick me leg out "accidentally" and whisk him off to Howarth. Job done - thanks for the tips, Mary!
