Frm what i rmb, he didnt betray penelope but he got brainwashed by that bij fl and thats how she returned to the estate. But by then penelope was alr v disappointed in eclis and she tried to distance herself away frm him. Eclis was possessive too
I dont remember the extent of how much eclis was influenced by the og fl but he brought back the og fl in the estate even tho he knew it would hurt penelope. Its like he wanted for penelope to leave the estate or get kicked out bec she was suffering there and just go with him. After this hunting competition part, there will be more interaction with the crown prince so i think ull like him more.

Tbh I haven't read it in a while but i don't think he was brainwashed (maybe he was) but he said he brought the bitch Yvonne or whatever her name was so that Penelope could get kicked out of the dukedom so that she only had him to rely on... Yeah talk about messed up. Anyway he just really wasn't it sorry to all the people who shipped them. Also Penelope never liked him and was just using him so he had a one sided love (and i kinda felt bad for him nearing the end but he wasn't good for her and just cuz he liked her doesn't mean she should return his feelings yk?)
Eclis is now my third favorite character ( Duke Eckert 1st and Penelope servants 2nd, crown prince 4th). So can someone spoild me if he going to betray Penelope (if he did ,what did he do) or not? I don't want to invest in him just to get my expectations shatter ╥﹏╥
