Bryan Dick picspam time! This time it's from Lewis, where he plays Phil Beaumont. I am utterly convinced that this is Jake Barton's more cynical twin, by the way.
I believe Jake has plenty more secrets he's hiding and another sibling could well be one of them. The discrepancies in surnames is no problem. For a start, Layla presumably has the same one as Jake and no one's noticed. For another, Phil's a writer so it's more than possible Beaumont is a penname. And it fits with Layla's character too. Beautiful blonde-haired, blue-eyed little girl, darling of the entire extended family, suddenly usurped by adorable baby twins?
