Well, that was a disappointment. It only took Gamzee a second to realize that Eridan wasn't going to reciprocate and so he pulled back and let go Eridan's face. His expression was unreadable for the most part, though there was a definite undercurrent of rage that Eridan could see as Gamzee carefully studied Eridan's own face. He was too unsure of himself and too nervous to say anything, he felt some kind of rejection already, he didn't want to hear it too.
Still Gamzee didn't want to give Eridan a focus on something else either, so rather than move the wand in a different direction - the smart thing to do - he left it as it was and hoped he hadn't screwed up enough that he'd soon have to flash step as far away as possible.
AND WHAT THE HELL I'LL JUST EDIT IT FOR A THIRD TIME
