Chris Colfer has revealed that his Glee character Kurt will have "emotional" storylines in future episodes.
Colfer told Zap2It that in the next instalment of the show Kurt tries to get closer to Finn (Cory Monteith) by setting up his father (Mike O'Malley) with Finn's mother (Romy Rosemont).
"[The episode] kind of dives into his back story," Colfer explained. "He kind of goes for this diabolical scheme where he tries to create his own little Parent Trap, but it kind of backfires on him.
"I think [the plan's] genius, to be quite honest. I think he's brilliant, but he didn't really think it through. [He has] a few second thoughts because the relationship he was hoping to establish isn't the relationship that is established. There's a relationship established with Finn but it's not with him."
Colfer also revealed that Kurt's storylines will become more intense in future episodes.
"Kurt is just one of those characters," he said. "He goes through, like, a rollercoaster of emotions. He just goes through, like, a Meryl Streep movie of emotions. Whether it's him falling in love, falling out of love, just being who he is in his school... there's lots of emotional stuff going on for him."
He continued: "In fact we just finished filming our Lady GaGa episode, called 'Theatricality', and in that Mike and I and Cory, we film, like, the most emotional scene I think that's ever been on Glee. It was pretty intense. Reading it on paper I had no idea it was going to be that intense. Once I got into it, then I kind of realised, 'Oh, there's such a bigger meaning behind this. Oh my God, this is so dramatic'.
"I'm excited for people to see it. I think it's going to have a very positive effect."
