Yuusuke comments on how his "ticker's still not ticking" and that he guesses he should be worried about it. This causes Hiei and Yoko Kurama to laugh (an extremely rare occurrence). Yuusuke looks confused at first but then laughs along with them. Kuwabara makes a goofy face as per usual XD I hope to add his doofy layer to this cel someday but it's pretty small and may be lost forever :(
The sketch is stuck but it's a great moment and the lines are so crisp ^_^
