Earlier in the day, Gwenaëlle had been negligibly dressed for the express intention of sunbathing; not noted for her frequent participation in morale boosting enterprises or (more specifically and pressingly) large social gatherings, laying in the sun and occasionally humouring Stephen's little golden paste had been about the extent of her joining in. Her presence at Abby's side is motivated twofold: to be a presence, not pressing, in case that's what she needs. Also—

Abby has very large muscles and an expression that suggests not approaching her. It's not not a perk of sitting here, drinking red wine a little faster. That having been said,

it is easy enough to shrug off the bear slanket she's wrapped around herself for the evening, nearly stripped enough to run to the water in one move (she is also pulling her chemise off over her head), the roadmap of her scars long since become too ordinary to her to hesitate at public semi-nudity,

“I'm in.”
