For me Bern choosing option 1 would be kinda stupid, she loves May and want to see her faster so to do that she will willingly cheat on her with random strangers for whole night to make that happen?
And we talk about a person who is a shy monogamous lesbian who so far had 2 sexual partners in the comic with who she was intimate which based solely on the romantic feelings they shared(we could also add Polly here as 3rd unrequited option), and who is also easy embarrassed by even her friends or associates seeing her nude body, and now such person would be forced to undress herself and spend whole night of becoming sexual slave(which means vaginal, anal and also possibly oral sex, or even double penetration and all that without considering her anything other than a piece of meat to fuck) by random group of guys.
Question is why Bern need to meet with May right away, I know Bern loves her, but that is childish and it's her biggest weakness, she should just grit her teeth, acknowledge that she fucked up and take the punishment as real warrior to climb the rank normally using only her skills and not the selling her body or injuring it or killing someone else for the shortcut promotion, choosing that would be showing she is indeed weak.
After all Polly will go out earlier than her, she just can ask Polly to give May a message and then they could go back here and pay for Bern marks if needed.
This whole drama if you will read from start is basically over nothing.
So what, Bern will see May 6 months or even later than with original plan(cause even if she is rank D with two magical swords and changing her attitude towards fights for real she will climb back fast), is Bern so insecure in her love with Maytag that she thinks May will find someone else during that time enough to accept one of the crazy deals which would make her giving important part of herself over literally nothing?
Cause even once Bern didn't think how this would affect her own life, just it's all over I will see May later than planned thing.
She needs to become a bit of selfish person. An individual should not degrade herself so much over love for another where it's not needed and it is not life threatening situation for both.
Seeing how Warden played this all out into cornering them, Bern and Polly should just take a break, breathe in or two and resolve this like thinking adults.
But seeing Bern reaction from last panel looks like the decision will be made soon one way or another.
