I have picked a humerous thread of Hermione and Duncan in [5:5].
Lady Dorothy proposes to put up her Eco-dome as a visitor attraction to bring visitors to the region. One problem is that she requires an access road through the Glenbogle Estate. She finally gets Archie to reluctantly agree to this.
In the meantime Hermione entices Duncan to become Manager of the Project much to the disgust of the others at Glenbogle.
He meets with the workmen which they are not entirely happy and he tries to soften them by telling them that he is not The Boss must all work together. He tries to pacify them with getting some bonuses - which fails. They have fun with him by lifting him up in their digger!
Later we see Hermione making loving advances to him which he obviously enjoys! However later whilst looking at documents about the Project on her computer he finds one with a wedding scene with them together; this shakes him up...
In the meantime Lexie gets her suspicions and sneaks into the house whilst Hermione is enticing Duncan up to her bedroom. Duncan finds Lexie there hiding behind a curtain thinking that she is snooping on him and is annoyed and wants to get her out. He finally hides her from Hermione by forcing her into a cupboard under the staircase!
Later Duncan finds the letter from the Glasgow Hotel (to whom he had applied for a job) offering him a job but Hermione had said the opposite - he then decided he could no longer trust Hermione, saying to her "you lied to me" and walks out on her, returning to Glenbogle.
Later on we see the public at a presentation by Lady Dorothy concerning the Eco-dome. The meeting becomes very noisy as Dorothy tries to point out how it will bring so much work to the area.
Duncan then reports that there is a Phase II which will not help the local people - this embarrasses Dorothy and Archie realises that he has been duped by her and says that we withdraws his support to the project.
Duncan then returns to Glenbogle hoping to get back his previous Head Ranger position only to find that it has been given to Jess... poor Duncan.
