In A Wedding Mason is seen dancing with Jane during Santana/Brittany and Kurt/Blaine's performance of Our Day Will Come.

In the episode Child Star a big spotlight was put on Jane and Mason when Mason starts talking to Jane more. He even asks her on a date to Breadsticks and teach her how to "eat her feelings" but the plan is cut short when Mason's twin sister Madison interrupts them. Later when the Glee kids were given an assignment to partner up with someone to sing with for Myron's Bar Mitzvah, Mason immediately looks at Jane. When Mason gets up to ask Jane, Madison jumps in and pressures him into being her partner. Mason brings the Glee boys into the locker rooms and asks them to distract Madison while Mason tries to ask Jane out. He explains that Madison always treated him like a small child since they were kids and he can't function. Both Spencer and Roderick refuse to help Mason because Spencer is gay and Roderick does not want to partner up with her after Mason explained how crazy she is.

After his plan fails, Mason goes up to Jane and asks her if she wants to go on a date with him and if she wants to be his partner for the Bar Mitzvah which Jane replies asking if Madison will be there. Mason flirts with her and Jane agrees to be his partner as long as he tells the rest of the Glee Club. In the cafeteria Mason finds Madison and tells her that she is partnering up with Roderick while he is partnering with Jane. Madison disagrees with this and Mason goes on to tell her that hes thinking about asking Jane out. Madison tells him she won't allow it and that Jane is a stage hog which Mason thinks is crazy. He tells her that its not her choice and Madison overacts and ends up embarrassing him. Jane, having seen the whole thing, tells Mason that it would be best for everyone if she just partnered up with Roderick and leaves Mason looking upset. At the Bar Mitzvah, Mason performs I Want To Break Free showing that he is breaking free from Madison's controlling ways and that he is in love with Jane who looks shocked throughout the entire performance. When the song ends he immediately runs up to Jane and hugs her. Madison tells Mason that she agrees with him and she gives him the space to be with someone. During Break Free, we see Mason and Jane exchanging a look to each other. In the end of the episode the Glee Club performs Cool Kids where Jane and Mason sing together and look happy.

In The Rise and Fall of Sue Sylvester, the Glee Club performs Rather Be and during Jane's last solo line she glances over to Mason and smiles. In the end of the episode when the Glee club and Warbler's sing Rise, Mason glances at Jane a few times. After this it is unknown if they are in a relationship.

They are also seen sitting next to the other while Will sings Teach Your Children, Mason is sitting next to Jane and her hand is on his thigh, implying that they are in some sort of relationship.

Mason and Madison about Invitationals., The Hurt Locker, Part One

I can teach you how to eat your feelings.

Mason to Jane., Child Star

How did this become about you, guys?

Mason after asking for help to Roderick and Spencer., Child Star

Mason: I'm kind of a badass
Jane: The only badass I know who's a male cheerleader
Mason: Well, you know what they say about cheerleaders
Jane: What?
Mason: Um...Good things, mostly.

Mason and Jane., Child Star

Mason: Look, I already know what you're going to say
Madison: No, you don't; listen, your performance up there was very moving and it reminded me how gifted you are and how crazy I've become
Mason: You're not crazy,
Madison: Mhm
Mason:: Look, a little nutty
Madison: I'm not gonna lie, I was terrified and jealous when I found out that you had an interest in Jane, because I couldn't stand the fact that I wasn't the only lady in your life anymore; the truth is I'm actually kind of relieved: You don't need me anymore...and maybe you never did
Mason: I'll always need you Madison, I just need a little bit more room for other people so you're not the only person in my life
Madison: I'm just so used of taking care of you and looking after, and it's not really because I wanted to, but because I felt like I had to.
Mason: You know I'm a better person because of you
Madison: Yeah, well, I'm a better person because of you

(They laugh and share a hug)

Madison: Okay, but I'm just going to say that Jane's a total stage hog.
Mason: Madison!
Madison: Well, she is!
Mason: Come on!
Madison: She is!

(they laugh again)
