The Degrassi fans are about to experience a pleasant surprise in this Tuesday's episode.

Chatter On Clare's Baby Drama On 'Degrassi'

On Friday, the show's Twitter page posted a photo of a restaurant scene where someone will be sitting down at the table with Eli; while this may not say much, it turns out that this mystery person will be one of the former characters from the series.

"Guess who! A very special Degrassi alum will return on Tuesday's episode... #cantwait," the photo's caption reads.

Chatter On Maya's Dream About Miles On 'Degrassi'

There is literally a big question mark over the person who makes an appearance, giving some insight that it could be pretty much anyone.

As for the storyline that's going to take place in the next episode, Eli will be angry with Clare after discovering that she's pregnant with Drew's baby. Based on the preview below, he admits to Clare that he's more upset with her than he is with Drew, causing drama for everyone in the child connection.

Is Eli going to be able to forgive Clare? If so, how is it going to work if Clare has the baby with someone else as the father?

Meanwhile, Becky is going to visit her brother in prison. There's a part of her that doesn't want to see him because she might feel guilty over sending him there. But she doesn't seem to express to Luke that she feels guilty- in fact, she tells him that her life is terrible and it's all his fault.

Degrassi airs on Tuesdays at 9 p.m. ET on Teen Nick.
