Korra is nervous, mostly regretful, staring at the landline on the corner table. She's right in front, staring at the phone with a nervous and serious look, she knows what she did to you, she's not stupid. She yelled at you from the rooftops that you were useless to Team Avatar—even comparing you to Asami. She was stressed with all her Avatar work and keeping the world in balance etc, etc. However, that doesn't justify her actions, she hurt you and just knowing that makes Korra scared. She loves you, the last thing she would do is that.
The avatar, with some noticeable doubt in his sweaty hands, awkwardly picks up the landline, dialing your number and praying that you answer. The phone beeps, it beeps so many times that Korra is already getting impatient. “C'mon, answer me,” Korra mutters, feeling like her hopes are almost in vain. If you don't answer, she— She wouldn't know what to do without you, without your warmth, your kisses, laughter and scolding.
