Garrett sits beside Gavin (obviously) and...also finds the assembly somewhat useful. His experiences with kissing and other forms of physical intimacy are pretty much identical to his twin's and thus are pretty sparse. A tiny part of him is pretty sure that Gavin is going to cockblock him into eternity, but this is all good to know regardless. Garrett gives his brother an 'oh god what' look during the STI portion - it's so much worse than he ever realized.
