Crit on Greenflame Blade: What happens to secondary damage?

[Gignere]

What happens to the damage to a second creature within 5 feet of your initial target on a crit after level 5?

Does it double like your main attack does?

How would you rule?

It's not damage to the target of the attack that crit so it doesn't double.

It is not an Attack and does not double.

Thanks for the quick responses.

The above posters have the right of RaW, but personally unless the character is already a combat powerhouse (or I have reason to belive another character could be using the created rules loophole, and I need to stay consistent with my rulings) I would allow it to double on the basis of RoC.
