A Rip in Time - S1.E1

Logan goes back in time to 1888 in London to keep the faux Jack the Ripper from changing the future. He discovers that the faux Ripper's plan is not to repeat the original path, but to continue killing women, thus drastically changing the future. Logan manages to send a message to the future by using a drawing of the faux Ripper that the possible next victim drew to send a finger print and a tiny message from himself, the words ""Logan's Graphics"", that not only let those waiting in the future for him know that he was OK, but who the faux Ripper was. The show ends with a showdown in Big Ben where Logan defeats the faux Ripper and returns to the future. The past remains relatively the same and the danger is, for now, at least, safe.
