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

Hi, maybe some of you won't even listen to me cause the pergunta 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 you if something interesting happens between bones and Booth between the half of season 4 and season 5. Maybe I'll find it out por myself :)
One mais thing: Don't say too many things, just yes, OMG it's gorgeous xD or no, everything goes ahead in the same way since season 1 (hate this!)
Thank you so much, guys :D
xx,
Connie
