Nobody knows what the agent said to Maja... for all we know, it could have been, 'hang fire for a couple of weeks, to see if something you'd like better comes along' or 'hang fire, I reckon there's another £2k a week in the deal, for you'. I have no idea how smart Josh is, how fiscally prudent or experienced he is or how much he trusts the judgment of his agent. My guess is that, neither does anyone else. Alternatively, Josh might think the grass is greener, elsewhere and is keen to sod off, or, again alternatively, his agent is exploiting him.
I think that the timing sucks, though (although it may be the case that there's no such thing as the right time for something like this).
