Ehhh, that's not really a question I can answer. That was a while ago- plus, our Egon's the one who took the actual readings. And Ray's the one who went down in the sewers alone to find the source of the slime.

Huh. So basically: our Egon had a tragic backstory, but you just wanted to make ghost bombs.

[Venkman's been around Egon enough to know what "harnessing x for my own purposes" means.]
