Blake stood there, he wanted to walk her up, but knew that it would be screaming the obvious; something he wasn't sure he was ready for just yet. Did he like Lily as much as he now believed he did? He knew the answer to that, but wasn't sure he wanted to make it any bit obvious to Lily. So he pulled another nerve, and made a decision, after long thought, that it would be best for his sake that he not validate his feelings, yet. Lily's rejection would burn, and Blake wasn't ready for that type of pain. He definitely wasn't ready to commit so easy, after having only just met met her on the whole.
Strewing his feelings with his expression, he finally said, "Alright then, I think I'm tired and in need of rest." Adding a fake yawn which he hoped would not give him away, he gave her a nodin farewell and made for the stairs leading down to the next floor.
