Telekinetic Charge and Ready

[Korahir]

Dear wise, people of this forum,

I stumbled upon this rule conundrum. Maybe you can falsify (or verify) my interpretation and offer the correct sequence. The following is happening:
Enemy A (a mid level caster without any contingencies) is in sight of Caster B and Melee C. Everyone rolls initiative: Caster B and Melee C have higher results than Enemy A.

- Caster B moves and uses Ready (Standard Action): When Enemy A is starting to cast a spell, I want to cast Telekinetic Charge targeting Melee C.
- Melee C moves (in range of Caster B) and buffs himself.
- Enemy A starts his turn and wants to cast a spell as a Standard Action and a quickened spell as a Swift Action.
- Ready Action of Caster B triggers and launches Melee C right next to Enemy A.
- Melee C uses an immediate action to attack Enemy A.
- ???Enemy A rolls Concentration against possible damage taken twice. (Once for the standard spell, once for the quickened spell)???
- ???Enemy A rolls Concentration to cast defensively twice OR Melee C makes an attack of opportunity because Enemy A triggers is by casting next to him (possibly twice if it is a ranged touch spell).???
- Caster B ends up with an initiative score right before Enemy A (according to the Ready Action).

Is this sequence correct? Where am I horribly wrong? The ones marked with 3 question marks is the point, I can't wrap my head around. What I am sure is that my original thought: Melee C readies an attack when next to Enemy A, is not possible because the immediate action attack used by Melee C clashes with the readied action rule that you cannot take any action before your ready action.

No.
Melee C's immediate action attack on Spellcaster A is not being made due to his own readied action to disrupt spellcasting. See the Combat Section of the Core paragraph titled "Distracting Spellcasters". Melee C does not meet the stated criteria.

Melee C's immediate action completes before Spellcaster A's casting.
Spellcaster A doesn't have to cast defensively with his quickened spell, because of the rule "Casting a quickened spell doesn’t provoke an attack of opportunity." See the rules entry for the metamagic feat. If the quickened spell involves making a ranged attack, that ranged attack can still provoke.

Now Spellcaster A's standard action casting attempt can be made. This attempt WILL provoke, unless it is made defensively. Succeed or fail at the concentration check, defensive casting does not provoke, but the spell is lost on a failure. If A elects NOT to cast defensively, then if C's AoO connects, A will have to make a concentration check because he took damage during casting. Assuming the spell goes off (either due to a miss on the AoO, a success at casting defensively, or a success at concentrating despite damage), if the spell involves making a ranged attack, that ranged attack can still provoke (again). However, no further concentration check is required.

So if C has Combat Reflexes *and* both of the spells A casts are ranged attack spells *not* cast defensively, C could potentially get 3 AoOs. However, only one would cause a concentration check for taking damage while casting.

Thanks for your answer. I agree on everything and realized parts of it already myself. Let me try it in a correct way and see if you find more mistakes:

- Caster B moves and uses Ready (Standard Action): When Enemy A is starting to cast a spell, I want to cast Telekinetic Charge targeting Melee C.
- Melee C moves (in range of Caster B) and readies standard action: I want to attack Enemy A when Enemy A starts to cast a spell.
- Enemy A starts his turn and wants to cast a spell as a Standard Action and a quickened spell as a Swift Action.
- Ready Action of Caster B triggers and launches Melee C right next to Enemy A during the first spell cast (quickened or not).
- Melee C uses his readied standard action and attacks Enemy A.
- Melee C uses his immediate action to attack Enemy A (He cannot take the immediate action before his own readied action according to the Ready section).
- Enemy A rolls Concentration against possible damage taken for whatever spell (quickened or not) he chose to cast first, possibly losing that one.
- Enemy A rolls Concentration to cast defensively if he did cast the quickened first OR doesn't roll because of the quickened metamagic rule.
- Caster B and Melee C end up with an initiative score right before Enemy A (according to the Ready Action).

Since the distracting spellcasters section states "if she starts casting a spell", the trigger of Melee C is now legal. The Immediate Action also targets the first spell because it is tied to Caster B's ready action. Any holes in that plan?
