Twilight: yawn
Flash: Heh, tired?
Twilight: Yeah… It's as if the child put a sleeping spell on me.
Flash: Haha, don't worry. Just another three months.
Twilight: yeah… sees Solar coming towards them Oh Solar! Would you like to come sit with-
Solar: No…
Twilight: o-oh
Flash: Champ, come on. You've been acting this way towards your mother since you heard you were going to be a big brother. Why? We thought you'd be happy to have a sibling.
Solar: I'm not mad about having a sibling!
Twilight: then what is it?
Solar: sniff I barely ever see you and you practically abandoned me when I was born! And now that you come back you decide to just have another foal to ignore and abandon?!
Twilight: Solar…
Flash: Solar Flare, your mother did not abandon you. You know very well she has an important job as a princess to-
Solar: I know! Protect Equestria, the citizens and blah blah blah! But you made no time for me and… you're going to put another pony through that…I just…
Flash: Solar your mom isn't going to be leaving as often…
Solar: what?
Flash: that's why we decided it was time for another foal.
Solar: …
Flash: Son, are you sure you're not jealous?
Solar: No. I'm sorry. I just… I sigh slowly walks away
Twilight: Solar…
Flash: Let him be. He didn't know you'd be around for the foal. I think it's a lot for him to take in knowing you'll be here from now on..
Twilight: right…
Solar Flare tends to get easily mad at his mom for "leaving" him as foal. Some of you may feel for him, others may think he's being a spoiled brat, but whatever the case, these were his feelings prior to his sibling being born. So do you think filly or colt? XD
