Etta is surprised to see Reid here for Seeker tryouts, but then again it's not like he's really taken to being a Chaser, is it? As for Penelope, Etta knows the other girl is a decent Seeker, but reserves never have the same level of experience even if they can match you on skill. So, she's not worried by the competition. She's here to have fun, and do what she does best, and she's practically bouncing on her heels as she waits for her turn to get in the air.
Doing drills that someone else has organised feels nice, kind of like how it was when Etta's big sister was captain and she didn't have to worry about the organisational and strategy side of Quidditch. The repetition allows Etta to fall into a zone of pure concentration, and that feeling of being ~one with her broom~ is glorious. For a while she actually forgets she's trying out for a team, as her goal becomes to beat her own personal bests and fly better than she did the last time.
When she finally lands, she's high on the endorphins that come with a successful workout. It wasn't perfect, but when she messed up she just focused on getting it right the next time, and she's happy with her performance. She's also really proud of how her friends and teammates flew today. No matter who ends up on the final team, they are going to kick ass.
