σὲ ἐπαναθεασόμενος ᾖα ὁποῖός τίς ποτε φαίνῃ ἰδεῖν ὁ τοιαύτην ψυχὴν ἔχων
I was going to see you again, what kind of person you having such a soul should appear to look at. This is probably deliberative subjunctive. φαίνω ἰδεἶν means to appear as to being seen / in eyesight, or something like that.
No, not a deliberative subjunctive but present indicative. A deliberative subjunctive could not work here. The ἰδεῖν is limitative, as in θαῦμα ἰδεῖν/ἰδέσθαι (a wonder to behold), καλὸς ἰδεῖν, (beautiful to see). Make sense?
Yes, thank you, I have also checked Goodwin MT who says that con delib is not used at all in the second person.
