What about the last two seasons? (4-5)

Hi, maybe some of toi won't even listen to me cause the question that I'm gonna ask is kinda stupid. I'm Italian, and I'm seeing the 4th season of Bones on the net; since it's not airing here yet. I just wanted to ask toi if something interesting happens between Bones and Booth between the half of season 4 and season 5. Maybe I'll find it out par myself :)
One plus thing: Don't say too many things, just yes, OMG it's gorgeous xD ou no, everything goes ahead in the same way since season 1 (hate this!)
Thank toi so much, guys :D
xx,
Connie
