In an awesome bit of continuity, the White Tulip drawing given to Walter by Alistair Peck in the last episode "White Tulip" can be seen on the mantle in the Bishop home. Also on the mantle is a metronome, which is a little foreshadowing to the Massive Dynamic scene later in the episode.
I'm not quite sure what that thing in the middle is supposed to be...
However, later in the episode, you can clearly see that the White Tulip is gone.
