Xander took a step back when Spike came over and pulled the banister off with no problem. OK, so... that was why supernaturals could be handy. When they were not eating you or pulling out your eyes or over all making your life a mess.
"Well, see... even though I do run my own business so I could set my own hours, I prefer some sunshine. Which my client seem to prefer to. She seems to be one of those awake during the day and sleep during the night people. And I see no ring or amulet on you." So even though he technically could use Spike's strength to his advantage... there were the problem of Spikes nocturnal habits... And Xander could not even believe he was considering hiring him. I've gone mad, Xander thought. Very mad.
