I like to have Spike back on the show, because he is funny even if he`s evil at this time.
At this time of season 1 there are several visits from characters of Buffy on the show for promotion I guess, but I think Angel didn't need it. It is a show of its own and the actor were doing just fine.
It`s a very sad moment when Angel destroys the ring so that nobody else can ever wear it again.
Doyle is funny as always, but also caring about the others and really good in protecting Cordelia in front of Spike.
I love that episode and enjoy watching it over and over again!
