Doctor Foster fans have called on producers to orchestrate a
crossover with fellow BBC drama The
Missing after last night’s episode ended with a character
vanishing.

Viewers watched as Gemma Foster (Suranne Jones) and ex
husband Simon (Bertie Carvel) were left reeling after
discovering their son Tom (Tom Taylor) had run away in the
final minutes of the show. 

The dramatic cliffhanger prompted excited fans to joke that the
‘only person’ who could find the teenager is Julien Baptiste,
the hardened French detective from The Missing.

One wrote: ‘That ending was definitely setting up a third
series with the missing and there’s only one person who can
find tom #DoctorFoster,’ alongside a picture of Baptiste.

 Another tweeted: ‘Right, I need a The Missing/Doctor
Foster spin off because the only man that can solve this
is Julien Baptiste.’

A third wrote: ‘A third series of Doctor Foster and The Missing
could be quite an incredible mash-up though.’ 

The episode kicked off where the penultimate installment ended,
with Gemma looking like she’d knock her ex husband down, but
she swerved at the last moment.

As the episode progressed it looked as though Gemma was finally
moving on with her life Simon tracked her and Tom down and
pleaded for his forgiveness, but Tom denied him.

Simon made one last ditch attempt to win Gemma back but despite
his pleas she told him she’d be happier if he was dead.

It was a case of be careful what you wish for as the failed
businessman was later seen just inches away from a busy
motorway, threatening to take his own life.

After saving her estranged husband Gemma informed him that she
and Tom wanted him out of their lives for good over a last
supper in a service station cafe.

It was there that Simon finally revealed what he had told their
son to make him hate Gemma – she had suffered from post natal
depression and tried to abandon him as a baby. 

After stepping in to stop ex-husband Simon from killing himself, Gemma rushed to see if her son Tom had also tried to kill himself in the episode's final dramatic scenes

Following Simon’s confession, Gemma fetched her medicine bag
and wrote out a set of instructions for her ex to kill himself,
so he could do it out of Tom’s sight.

She managed to convince Simon to stay alive and went down to
the car park to drive home, but was devastated to find that Tom
wasn’t in the car. 

Gemma came to the conclusion that he had chosen to end his life
in the way his father had attempted to do on the motorway.

After failing to find Tom, Gemma reports him missing revealing
that she blames herself for not noticing how depressed he
was. 

The story jumped forward to when Gemma had returned to work and
life carried on, but there were missing posters around
Parminster, where they lived.
