Four incomplete lines in near-English appeared on east glass during Block 2. Finger-width. Not transcribed, not photographed by choice. Lines moved toward each other during the Block 3 Ace of Spades call. Stopped short of touching. Unresolved at session close.

Fine lines in the lower corner of the east-facing glass, forming from Block 2 onward. Not legible. Spread approximately two inches by close. Pattern more deliberate by Block 4. The Block 3 caller knew about the east window frost without being told — asked with the precision of someone confirming a known fact.
