It has been a turbulent few months for Karl (played by Alan Fletcher) and Susan Kennedy (Jackie Woodburne) on Neighbours.
The pair have had their world thrown upside down when troublesome Izzy Hoyland (Natalie Bassingthwaighte) reappeared in Erinsborough.
The blonde bombshell demanded Karl gave her a sibling for Holly (Lucinda Armstrong Hall), a love child he created many moons ago.
Although her scheming ways seem to have ended, thankfully without Karl doing anything he regretted, there is more trouble coming up for him and his wife.
The medical man gets involved with a medical trial at Erinsborough Hospital which throws up a big bombshell.
Next week, Karl is diagnosed with deep vein thrombosis after finding himself wrapped up in learning the results.
He has a look at the work already finished and realises a participant’s test may have been wildly misinterpreted.
Should it have gone unrecognised, the consequences could have been disastrous.
It seems the diagnosis is evidence of a blood clot, which could prove fatal.
He desperately tries to find the owner of the results, but is completely horrified when he discovers it is, in fact, him.
Karl rushes to see Dr David Tanaka (Takaya Honda) jin secret to see what can be done for him.
It’s sadly true, however, and together they find the clot in Karl’s left thigh, which is most likely from his flight to London last year.
He is immediately put on blood thinners to help and he toils with the idea of telling Susan.
The former doctor ultimately decides not to tell his wife the truth – however, that doesn’t last long.
A kitchen accident means he must be rushed to hospital where he comes clean to Susan on his diagnosis.
With the pair already going through so much, how will Susan react to yet another lie from her husband?
The newcomer has already caused a stir but it seems that is just the beginning.
She told Express.co.uk although she means well, Chloe does have a “big mouth” that can get her into trouble.”
