Yesterday my gf reminded me of Lady Gaga's song "Telephone" and I've been thinking about it a lot tonight while watching earthspark s2 (kinda disappointing i know but i still gave it a chance) and when this scene came up i immediately had an idea for some MegOP drama happening hsjsjsjs
Hashtag doesn't know about his relationship with Megs- so she definitely checked the box that says that Optimus is single while creating his social media account (kinda looks like a dating app tho so that makes the MegOP drama even worse if it happened to be one)
So when Megatron happens to see that social media profile eventually (somehow) he would be very mad and, hurt. He'd definitely go hang out with Dorothy without telling anything to Optimus, getting him soon worried about Megs' whereabouts, and Optimus would process to call him over and over. But since Megs' not the best with communication he would just keep either not answering OP's phone calls or putting them down saying he's busy and cannot talk right now.
Also yes, Dorothy is definitely their wingwoman. At first when Megatron comes over he doesn't want to tell her what's wrong and just shifts subject constantly, but Dot can see that there's something up and has to do with their relationship. Also Optimus at some point calls her too to ask if Megatron's with her hsjsjsks
OP has no clue what's wrong until either Megs gets mad asf through the phone and spills it out then hanged up on him or Dot tells him after Megs told her what's wrong. Usually as soon as Dot realises Megs' not-good mood is due to Optimus, she starts saying "Go talk to him. Please, Megs" because she knows that's the solution to any relationship problem. Go girl!!!! <3
