Doctor Who: 10 Things That Make NO Sense In The Modern Series

10. Dalek Caan Lets His Allies Die For No Reason

It's no secret that the Daleks are hard to get rid of. They're tough, merciless, and have a habit of surviving everything. They're basically the cockroaches of the universe.

However, they're not invincible. Just ask Dalek Thay and Dalek Jast, who were blown to bits at the end of Evolution Of The Daleks when Dalek Caan just sat back and let them be exterminated - even though he was in a position to stop this from happening.

During this episode, Dalek madlads the Cult Of Skaro end up creating some Dalek-human hybrids, but when the Doctor interferes, some of his Time Lord DNA is inadvertently thrown into the mix.

This gives the hybrids a bit more humanity, and because of this, they ultimately turn against the Cult and kill two of its members - Dalek Thay and Dalek Jast.

Then, right after this happens, Dalek Caan - who is safely back at base camp, observing this whole situation - remotely kills every single hybrid by activating an implant inside their heads. But hold on: why did he wait until Thay and Jast had died before utilising this rather useful weapon?

Prior to their deaths, Thay and Jast engage in a gunfight with the hybrids for a good 20 seconds, during which Caan says "Destroy the hybrids!" and he could've easily triggered the implants at this time. But... he doesn't. Why? Who knows. Instead, he just sat and waited until his mates had died first. So much for "The Daleks must survive!".
