As with Bill coming back from Dipper's mind knowing what happened never knowing that he could fall in love especially with his enemy then suddenly Will burst through the door while he was still in bed while his sheets covering the bottom part of Bill's bare body "Will you better have a good reason to barging in or do I have to punish you once more; no place I do but first put on some clothes or in last shorts " Will said in a cocky and scarred way " I came to tell you that we have a problem it looks like that we are now protectors of the pins twins since he's the one you're in love with which you know what happens next; Will get ready for your punishment and you really didn't know that I knew of demons low that's only if my marking has appeared on him unlike you the marking has appeared on marble's neck little brother; sorry but you're wrong your Dipper now has your mark" Bill started stabbing and slashing Will as he screamed in pain "now after I'm done disciplining you explain everything to me that you were keeping secret then let's go surprise those brats" as Bill continued

morning came Mabel work up then headed down to feed the animals then Dipper started to come down as well when something knocked at the door "Dipper​ can you get that" she giggled suspiciously "okay but were we expecting any" all suddenly the slammed open before finishing his sentence then Bill and Will walk through the door then captured Dipper with his powers

B) I'm back did you miss me pine tree oh I should probably introduce you to my brother Will.

D) you have a twin brother!

W) charmed to meet you hello mabel my love.

D) Mable how do you know him and why did he call you my love!

B) clueless are we he's your sister's lover and protector I know even I was surprised now let's take that shirt off" looking at Dippers back with his mark then carefully touching it " so it's true and you're quite sensitive now.

D) what are you going to do mmmm. ( at that time his face turned red when Bill placed a soft but firm kiss on his lips then released)

B) you're adorable when you blush pine tree.

D) can someone tell me what's going on!

He said flusterly looking away from Bill after a while Mable explains everything that she had kept secret from him since Dipper would of over reacted and the puppet incident with Bill which he was still freaked out about it but she moved her hair showing the mark that she was hiding at that moment Dipper knew why Mable was trying to make him move on from the past and her showing feelings of love because she's in love with a demon even if he told her how crazy she is but he knows that it won't change anything especially for himself since he had the same feelings towards Bill.

After releasing him Dipper started to ask her when it happened she just replied "it was last month in college when it happened" " I wish you told me earlier now I have to tell you something as well" turning his back towards her " it appeared yesterday in the in the night right after my dream and I'm in love with Bill cipher!" yelling the last part while Bill stood there with a smirk " so that's why you were so flustered let's not keep any secrets okay awkward sibling hug; awkward sibling hug" "pat pat i love you bro"
