The first episode of All Creatures Great and Small season 6 saw Siegfried Farnon grappling with life at Skeldale House in the absence of Mrs Hall.

Initially, it seemed the pair had clashed over something, with Siegfried refusing to admit he needs Mrs Hall's assistance.

Deciding to intervene, James Herriot and Tristan Farnon travelled to Sunderland, where Mrs Hall had been residing with her son Edward, his wife and their daughter.

It turns out Mrs Hall had taken time off to help care for her granddaughter, and was eager to spend more time with her son following his return from service.

James and Tristan conveyed how Siegfried was struggling, but neglected to inform her that Siegfried was unaware they had come to request her return.

After agreeing to return temporarily to Skeldale to sort things out, Mrs Hall and Siegfried were taken aback to see each other.

Siegfried was noticeably irritable with Mrs Hall, who was puzzled as to why she was the target of his wrath.

It became clear that Siegfried had not coped well with Mrs Hall's decision to take a break, and he was still upset about her absence.

He was also reluctant to admit that he was finding it hard without her, which only fuelled his hostility towards her.

However, after recognising her as an invaluable asset and close friend, he persuaded her to stay on a permanent basis and apologised for his actions.

All Creatures Great and Small airs on Thursdays on Channel 5 at 9pm
