When Slade is shot and seriously wounded, Holly goes back in time, but is she warning him away from his attacker or driving him to the incident?

Can you change the past? The show has always stated that this is impossible. Holly is giving a lecture on that very subject at the time that Slade is shot. Why then, when she believes this so utterly, does she go back in time and what does she hope to achieve. She tells him that she won’t tell him what’s going to happen and then does just that. She is certain that she cannot alter what is to happen, so why is she even trying? It makes no sense at all.

The murder plot is OK, but nothing more than that. Throwing in the siege situation at least leaves Slade with a terrible dilemma as to whether he can walk away from a situation that he knows will leave him close to death when doing so will have incalculable consequences for others.

And let’s not even get onto the fact that the rest of the team act like complete fools and they even let Slade walk into the hostage siege without the simple precaution of a bulletproof vest. That’s something that he doesn’t ask for either, despite the fact that it must surely be standard procedure.

The final resolution of the conundrum is unsatisfying to say the least, even in such a lightweight entertainment show.
