Overall, i expect this team will do well. Donny we hardly know at all. Allison we know quite well from BB4, & most viewers will be hoping this team will stumble for an early exit.
However, Allison is a very good reality tv show contestant, being shrewd, focused & competitive with a little bitchiness thrown in. The key here is teamwork & how they will function together in completing tasks. If they have any degree of teamwork at all & if Donny is at least 1/2 as competitive as Allison is then i think this team will be very successful this season in advancing far along.
