i think Mcgee will upset Abby and then he goes to her lab and is like i'm really sorry then kisses her :), or he goes to hug her and shes like get away i hate you and starts hitting him then she cries and they have a moment and gibbs walks into abbys lab while they are kissing and gibbs is like whats happening here? or tony is like abby can you ....ill leave you two alone :L
