While Ted is kissing Blake, he starts to undo his tie. As Blake walks away, his tie is undone and in his next closeup, his tie is tied once again with only the top button of his shirt undone. For Ted's closeup, you can tell Blake's shirt is open wider and his tie is once again undone. A few minutes later in the bedroom, Blake is taking off his underwear to take a shower. He doesn't take his (black) socks off, but in the mirror's reflection, he has no socks on as he walks into the bathroom.
