Just thinking out loud perhaps she (Lindsay not Anna) has a little secret - like maybe she is pregant !!!!!!! It is just an thought coz don't your hormones go all over the place in the early stages. Plus we don't really have a time scale between end of Season 3 and start of Season 4. I know that the trip to london was for 3 weeks but there is no way that dannys injurys could have fixed that quick!
I don't think that is the case, at least I really hope not! I just think it was bad writing of the writers to make her all weepy like that.
The lack of knowledge about the time schedule makes everything just that more confusing. Plus that would make for some really bad drama for the upcoming season... I don't think neither Danny or Lindsay should have to go through the damage that would do.
