"Still wouldn't call my lapse in judgment an obvious death with, which is all that can be called that you're displaying lately," Wesley pointed out to him. He had no real hope of getting out of this alive, so he had no real reason to bite his tongue at the moment.
He tried to jerk out of the way when Connor jabbed him with the needle, still trying to get out of his grasp the entire way down to the basement. Wesley wasn't about to sit still while all of this was happening to him. He knew it was a futile effort, but he just didn't have it in him to sit still and wait to die. Coming back from the dead made him want to live, he supposed.
"Giles died because you came in and turned him into the thing he despised the most. Thankfully, he didn't get to do any lasting damage," Wesley remarked. Despite the fact that he could feel the drugs already starting to kick in, he tried to hold onto his psyche. He would need all of his wits with him, after all.
He didn't want to call out when the taser turned on, managing to only grunt the first time as his body shook, doing his best to keep his throat from pressing too hard against the knife. Yes, to just let the thing slice him open would have made this quick and anti-climatic for Connor, which would have been his final 'fuck you' to the demon that now inhabited the boy's body, but his will to live was fighting that urge.
