Date: BLT and VGF
After several dates, BLT was too practical and uninterested in any sort of splurge other than an extra toilet. VGF, OTOH, thought money was no object.
Marry: CCV
CCV was the best of both worlds. A little fun and fanciful, but still budget conscious and practical.
Kill: Poly
Poly didn't seem to care about money or practicality. Just wanted to party and light the money (err points) on fire.
