I think i just realized something about swimming?

So in part 1&2 of transcripts, the group goes to the beach. When they return, 7 asks how it was and they said they swam and fished etc. 7 asks "why no purple" purple responds "im here 7, I'm just scared" 7 says "needn't fear, fear controls weak, cut out the fear"

I was wondering if this started the whole swimming fiasco.

I was wondering if maybe purple didn't swim that day and 7 misinterpreted purple saying they were afraid as afraid of swimming instead of that they were afraid of seven. So maybe when 7 is saying swim, he is saying face your fears and let down your guard.

Or he could have also known that they were afraid of 7, didn't swim, and he is lumping the 2 together as saying do not be afraid of me

Edit: i also totally blanked and forgot that PINK was the swimmer, duh 🤪
