Aye, you're probably right. I just like to think that he hasn't. I don't trust Ashley one bit so would quite expect her to make Lucas think that he has slept with her. Since he was drunk at the time the alleged situation took place, he may be using what she told him as 100% fact. That is likely just me wanting him to be ¨Mr. Nice Guy¨ though!!
Regardless, I can't wait to find out how it will all turn out. It's clear that Storm does still have feelings, but as you say, it all depends on how far he'll go.
