Sabine Bassard
Sabine honestly didn't expect that reaction.
She essentially called out April for being a weirdo and hiding her true feelings while also insulting Sabine and yet, the girl was falling over herself, apologizing profusely and denying that anything was wrong. It threw Sabine for a loop. Typically, this is the point where the other girl would fight back, call Sabine a bitch, or the usual mean girl fanfare. This was unexpected.
It intrigued Sabine.
Sabine did not know April well enough to know if the girl was telling the truth or not, but Sabine prided herself on her ability to read social cues and make her own estimated deductions. And she knew April was not "all right". Far from it. There was pressure underneath, but if April wasn't ready to talk about that with an almost total stranger, Sabine could not blame her.
After the girl rambled on for a bit, which was amusing and cute, Sabine decided to put her out of her misery. "It's okay. I was mad, but I am not anymore. Just...be more mindful later on. It's a touchy subject very few people are allowed to comment on, let alone joke about."
April checked her phone as Danny called out to them, attempting to put more stock into what this conversation was than needed (she would see Danny paid for that later), but April seemed panicked. Dorian, the birthday boy himself, was ready for them and if April's reaction was anything to go by, in trouble. It wouldn't surprise Sabine if Dorian possessed another person in an attempt to fix silly mistakes.
Sabine was prepared to follow when she heard a crackling sound, followed by a shark CRACK as the Dunk Tank exploded, sending water and shards out. Sabine instinctively held her arms up before it was deemed safe. "Holy...." was all she said as she looked at April, who was even more panicked. Coulson, though, appeared unharmed.
Taking matters into her own hands, literally, Sabine ran up to April. "He's fine, you're fine, everything is fine. Take some deep breaths and let's go see Dorian." Sabine grabbed April's hands, squeezing before leading the girl away from the dunk tanks and following Danny and Mai to Agatha's Tent.
