Gotham Season 5: 5 Major Questions We Have After 'Ruin'

Contains spoilers from Gotham Season 5, Episode 4.

Gotham returned to screens earlier this month with an explosive premiere episode - one which spectacularly set up the final season's No Man's Land arc. The hit Fox series has quite frankly been unmissable this year, with each episode delivering shocks and twists at every turn. The latest instalment, Ruin, is no different, as it proved to be one of the series' finest hours to date.

Selina Kyle had much of the focus in this one, as she continued her mission to track down Jeremiah Vaelska and exact bloody revenge for what he did to her. The future Catwoman managed to achieve her goal, as she came face to face with her attacker in a showdown that had huge ramifications for all those involved.

It wasn't just about Selina, however, as - after being absent from last week's episode - Ed Nygma showed up at the GCPD looking for answers. Much like the last time we saw the riddle-obsessed lunatic, his blackouts were still proving to be a problem for him.

Overall, Ruin was another enticing episode. Much like its predecessors, however, the instalment has left us with a lot to mull over until next week's outing, so let's get started...

Barbara Kean and Jim Gordon have had quite the colourful relationship on Gotham. They were sweet and innocent lovers when we first encountered them way back in Season 1, but Barbara's mental breakdown completely changed her character's personality - some would say for the better - leaving her on the opposite side of the law and as far away from Gordon as humanly possible.

As the two characters have been literally left with nothing to live for in Season 5, it's no surprise that they've hooked up. Having said that, when you consider all the hurt and heartache they've both experienced, it's no surprise that many viewers considered this pairing to be dead in the water. Ruin's shocking conclusion disproved this theory, however, as Gordon and Barbara kissed - a moment which left a lot of us with our mouths ajar.

The big question is if the GCPD captain simply gave into temptation, and allowed himself to bend the rules for a bit of fun. If this is the case then no-one would blame him considering he's been left with nothing and nobody. However, as the two were once in love, could this passionate kiss be something deeper?

Should the show want to follow comic canon (although it rarely does), then the source material dictates that Babs and Jim need to be married so that Barbara Jr (aka Batgirl) can be born. However, given that this is Gotham we're talking about, a one night stand would likely suffice.
