[clarke is a bit too caught up with her panick to realize she wouldn't drown underwater despite her lack of experience not have the ability to breathe and talk to other people too.
she doesn't even notice lance approach her until she hears him talk which mostly catches her by surprise but hearing his words as she tries to help her, she just nods and tries to focus on calming herself while still attempting keep afloat]
this is all good!!
