Magath: because of your emotional flaws by how your always angry with someone even when it's constructive criticism.(Y/n): I don't do that ever and you better watch it before I transform and this whole place up. Magath:you better watch your tone Eldian garbage
(Y/n): I'm sorry sir. Marcel: (Y/N) time to go. (Y/n): ok cmon lets go it was me Marcel,Annie and Porco. (Your gonna understand why I did this I have plans)

Time-skip

We were setting up camp when a Titan came out the ground marcel got grabbed but porco pushed him out the way that's when I realized that this was gonna have the armored titan power but we were all to scared to do something so we were cowards and we ran except me I just stood there and told porco to transform and he did right before he got eaten they all came back looking at the ground in shame porco got out of his Titan form and looked mad(in this one Ymir never gets turned into Titan but I have a plan for her) porco told us we were wimps except for me he thanked me for the idea to transform I said your welcome and we all went to bed
