She's not all that well liked in the house she thinks she is.

I think she has shot her bolt now.

What does that mean?

I think both Tara and Darryn are plotting and getting people to align with them. With Tara it is more obvious but Darryn does it in a sneaky way
such that the victim does not know they are being manipulated.

On last nights show it seems everyone is plotting/scheming.

I can see Tara and Kerry clashing at some point, dunno why
