The bank-robbers known as 'Charmers', who pulled off 16 robberies without any violence, even courteous, are studied by Charlie, who correctly predicts their next place and time to hit, but Donny's SWAT team is caught in a shooting with casualties at both sides. Donny is lightly hit physically, but Charlie can't handle 'failing' and putting his brother in danger, feels guilty, says the equations are no longer valid because of the Heisenberg-principle (observation changes the phenomenon, and the smart robbers even realize it), but is unable to concentrate on anything else then an unrelated, impossible maths problem. Left to its own, Donny's team discovers the shot bank-robber wasn't bank-employed programmer Malcolm Stapleton as his ID says: the criminals, who probably have a military background, stole the real one's identity, after torturing and murdering him. Charlie snaps out of his escape-maths and realizes the robberies aren't about cash but even more valuable financial data... Written by KGF Vissers

Charlie helps his brother again!
4 May 2008 | by (Brazil) – See all my reviews

In the second episode of 'Numbers', Charlie is recruited again by Don to helps him in the mystery of which bank will be the next victim of a band of bank robbers known as 'Charmers'.

Charlie has success in finding the bank, but when Don and his team has a deadly battle with the bank robbers, in which civilians and agents where hit or killed, Charlie decides to drop the case to focus in complicated and impossible mathematical problems.

The reason why he did this, is explained later in the episode to be his fear of losing his brother, since he doesn't want to put anyone in danger. (Charlie has problems in showing his emotions and concerns for people he loves or likes.)
